Providing tools
|
|
| |
The
analytical instrument business is really about providing people with
tools that help them achieve success in their work. Tool usage is
typically considered to be a sign of higher intelligence and, for
those of us involved with analytical instruments, there may be a
tendency to think of ourselves as pretty high up the intelligence
ladder. But there are many examples of tool usage by primates other
than humans and when you examine their use of tools you have to
wonder how far we have really come; the problems we are trying
to solve might be more complicated but the type of questions we are
trying to answer are very similar.
The accompanying photo captures a gorilla using a
stick to measure the depth of a pond that it is wading into; the
depth of the water is of critical interest as the gorilla does not
want to drown. Depth, distance, or length: aren't these the same
questions many of us ask in our use of analytical instruments?
From the person working in a semiconductor fab who uses XRF to
measure thin-film depth, the structural biologist who uses X-ray
analysis to measure the geometry of the active site in an important
enzyme, or the gorilla crossing the pond—fast, accurate knowledge
of critical parameters can mean the difference between success and
failure. At Rigaku we are dedicated to helping you predict your
success by giving you the tools you need to cross your own river.

Rigaku
Americas Corporation is pleased to announce that the NANOHUNTER
benchtop total reflection X-ray fluorescence (TXRF) spectrometer has won
the 2007 R&D 100 Award. Presented annually for 44 years by R&D
Magazine, the R&D 100 Award is a mark of excellence known to industry,
government, and academia as proof that the winner is one of the most
innovative products of the year.
The NANOHUNTER was specifically designed
to offer comprehensive trace element and materials characterization
analysis capabilities to a broader range of research disciplines, and in
more diverse analytical settings, than was possible with previous
technology. Whether for geologists, chemists, biochemists, biologists,
materials scientists and engineers, non-destructive trace element analysis
is attainable, with minimal to no sample preparation, for applications
that span from metallo-protein research to environmental assessment and
semiconductor wafer metrology.
Providing
both trace-level elemental analysis and evaluation of the physical nature
of the sample, NANOHUNTER uses a patented switchable wavelength and
automated variable X-ray incidence angle excitation design. The instrument
can analyze the full range of elements, from aluminum (Al) to uranium (U),
in solids, liquids, and powders. It also provides chemical information as
a function of analysis depth for profiling surface characteristics of
materials. As an example, for researchers involved in nanotechnology, this
ability allows surface layers to be characterized as particles on a
substrate, a homogenous thin film, or as something in between.
With sensitivity on par with inductively
coupled plasma optical emission spectroscopy (ICP-OES), NANOHUNTER
provides part-per-billion (PPB) level detection limits for liquid samples
in a fully automated tool. Halogens can be analyzed with high
reproducibility. Organic liquids may also be measured without sample
preparation and sample volumes as small as 50 microliters may be analyzed.
Direct measurement of solids and powders
provides freedom from complex sample digestion or preparation and makes
this spectrometer suitable for replacing or supplementing traditional
atomic spectroscopy methods. Compared to other trace level atomic
spectroscopy techniques, the revolutionary aspect of NANOHUNTER is in the
minimal level of sample preparation required. It liberates the operator
from ancillary equipment—like fume hoods and microwave digesters—associated
with trace element analysis in a wet laboratory environment.

ActiveSight® and Rigaku are organizing a
Fragment-based Lead Discovery (FBLD) Conference February 2008 in San
Diego. FBLD is a technique that utilizes smaller compounds and
libraries to screen drug lead chemical space more thoroughly,
leading to more tightly binding compounds than traditional
high-throughput screening. Fragment libraries can be screened using
biochemical assays, surface plasmon resonance, NMR, or X-ray
crystallography. Advances in high-throughput crystallization, data
collection, and structure determination have made crystallographic
screening much more achievable. X-ray crystallographers can now have
an even greater impact on drug discovery programs by creating lead
compounds using FBLD.
The conference's agenda has been put
together by a scientific advisory board comprised of FBLD pioneers
from ActiveSight, Astex Therapeutics, Novartis, Sunesis, and
Vernalis. The opening plenary speaker will be Stephen Fesik from
Abbott Labs, creator of the "SAR by NMR" method. The
closing plenary speaker will be Christopher Lipinski, formerly of
Pfizer, who determined the "Rule of 5" which is used
universally as a guide for druglike compounds. Along with speakers
from Plexikkon, SGX Pharmaceuticals, UCSF, and University of
Washington, among others, the conference will provide a forum to
discuss the status and future of lead discovery and optimization,
and FBLD's role.
ActiveSight and Rigaku have been
instrumental in the emergence of FBLD as a Lead Discovery
ActiveSight's Vicki Nienaber did groundbreaking work at Abbott to
establish that crystallography could be automated for fragment
screening, and was co-inventor of Rigaku's ACTOR™ crystal-mounting
system robot. Rigaku's ACTOR and powerful in-house generators
facilitate the rapid data collection needed for screening the large
number of crystals needed. ActiveSight uses the Ultimate HomeLab™ to
screen their Fragment library in-house. The data are then processed
by MIFit+ Rigaku's automated structural determination software that
was based on ActiveSight President Duncan McRee's popular Xfit
software. ActiveSight collaborates with its pharmaceutical and
biotech partners to screen their drug targets, and they also have
internal drug discovery programs. Rigaku's innovation in
high-throughput crystallization and crystallography has also enabled
FBLD at Astex Therapeutics, who have put several lead compounds into
clinical trials.
FBLD 2008 will take place at
Paradise Point Resort & Spa, a 44 acre private island in San
Diego. Emphasis will be placed on creating an atmosphere that is
conducive to scientists interacting. Exhibitors will also provide
information on complementary technologies such as surface plasmon
resonance, calorimetry, and NMR. An FBLD methods and implementation
workshop is also planned. For more information, e-mail ActiveSight.

Rigaku Americas Corporation introduced two new high-performance
CCD-based X-ray area detectors at the 24th European
Crystallographic Meeting (ECM24) in August. Optimized for macromolecular and
small molecule X-ray crystallography respectively, the Saturn 944+ and
Saturn 724+ were internally designed, developed and manufactured by Rigaku
as part of an on-going commitment to providing the most advanced tools for structural biology and chemistry research and development.
Bringing a new dimension to high-throughput data collection, with a 4-fold increase in readout speed (to 8 MHz total) and improved signal-to-noise and
dynamic range, the Saturn+ line of third generation Rigaku CCD X-ray detectors is optimized for high performance X-ray crystallography
applications where maximum productivity is essential. This new generation of
CCD detectors delivers extremely high readout speeds without any significant
increase in read noise compared to the previous generation of CCD based X-ray detectors. Both detectors employ the advanced Kodak® KAF-4320E CCD
sensor, incorporating transparent indium tin oxide (ITO) technology for superior sensitivity. A large format front illuminated sensor, optimized for
high dynamic range and superior spatial resolution, is coupled with a state-of-the-art high speed 18-bit analog-to-digital converter and 4 port
parallel readout to deliver low noise, a true 17,500:1 dynamic range and ultra fast readout times simultaneously for the first time in such a
detector.
The full-frame CCD sensor uses proprietary 2-phase architecture with large
pixels for wide dynamic range. To increase the sensitivity of the chip, one of the two polysilicon gates used in conventional CCD sensors has been
replaced with the transparent conductor indium-tin-oxide (ITO). This architecture eliminates the need to resort to backside illumination and
provides the intrinsically superior dark current characteristics needed to generate the highest quality data.
With a large 94 mm x 94 mm (133 mm diagonal) image area, the Rigaku Saturn 944+ is the definitive CCD X-ray detector specifically optimized for the
high throughput and spatial resolution needs of protein and macromolecular crystallography. For small molecule crystallography, the Saturn 724+
features a 72 mm x 72 mm image area (102 mm diagonal). Both detector systems
employ an extremely reliable closed loop Joule-Thompson cooling system (no water required) and an in-camera LCD status display panel.
Complementing the Saturn+ line is the Rigaku
Saturn
A200, the first "next generation" large area CCD detector to be offered. Incorporating a 2 x 2
array of the Kodak KAF-4320E CCD chips, with a 203 x 203 mm active area, the Saturn A200 brings a new dimension to both synchrotron and home
laboratory data collection.

Limestone
analysis with the Primini®
| |
MIFit+
software released
|
|
Limestone quarry lab
technicians are required to take samplings frequently and respond
quickly to certify product ready to release by truck or trainload.
The demand for limestone
is increasing due to legislation requiring sulfur dioxide flue
gas scrubbers to be installed in oil- and
coal- burning power generating plants.
Rigaku's low-powered Primini
benchtop WDXRF spectrometer is ideal for limestone analysis using a
pressed pellet technique. The analysis of light elements such as Na and
Mg can be performed with better sensitivity and improved element
resolution compared to similar EDXRF units and without the need of
higher-powered WDXRF systems.
A new application byte is
available on our web site that describes applicable concentration
ranges, sample preparations, calibration and analysis results.

ActiveSight announced
recently that it will collaborate on a Fragment-based Lead Discovery (FBLD)
Project with CHDI, Inc.
FBLD involves the binding of small compounds, "fragments," to the active sites of protein drug targets. The fragments are much smaller than the
compounds used in traditional high-throughput screening (HTS), allowing a more extensive sampling of chemical space with a smaller screening library.
Utilizing a Huntington Disease (HD) target chosen by CHDI, ActiveSight will
screen fragment libraries using X-ray crystallography to visualize fragments
that bind to the target. The fragments will then be linked or grown into larger, drug-like compounds that are thought to be more efficiently binding
than compounds resulting from HTS methodologies.
Several compounds based on Fragment-based Lead Discovery (FBLD) methodologies are currently in clinical trials, and the technology is
thought to shorten the time from drug target selection to an investigational
new drug (IND) filing. The two companies hope that the FBLD collaboration will lead to HD therapies in shorter time periods than conventional lead
discovery methods such as HTS.
ActiveSight's high-throughput structural
biology capabilities will facilitate rapid screening of CHDI's HD target
with hundreds of drug-like fragments. Automated data collection and
structural determination will be facilitated by Rigaku's tools for
high-throughput X-ray crystallography, including the ACTOR
crystal-mounting system and MIFit+
automated structural determination software. ActiveSight has leveraged
these capabilities to screen several drug targets with their proprietary
fragment libraries, and is pursuing lead development on promising fragment
hits. The CHDI project will be overseen by Vicki Nienaber, Ph.D. at
ActiveSight, a pioneer in the utilization of X-ray crystallography for
Fragment-based screening and lead development.
"We are pleased to have the opportunity to work with CHDI to discover new treatments for Huntington Disease," said Duncan
McRee. "We will work closely with CHDI's drug discovery team to turn
the results of our high-throughput FBLD screens into tightly binding lead compounds."

Rigaku's application
specialists are constantly using Rigaku instruments to test and
demonstrate their use and capabilities.
We recently decided to make
the results of these experiments available on our web site. To that end,
we are developing application galleries for many of our products. The
galleries themselves (for example, the
MiniFlex II gallery) are accessed by clicking on a button like the one
above in the right-hand margin of the product page.
The gallery lists available
application bytes by title. We call them bytes because they are brief and
to-the-point. They usually consist of a description of the importance of
the study, a snapshot of the experimental details and the major results.
Want to know the difference
between chocolate and cocoa? We have a MiniFlex
II app byte for that. Want to see how we can handle twinned samples?
There's an R-AXIS SPIDER
app byte for that.
We currently have over
seventy bytes on the web site, with more being added each week. If you see

The
ACTOR User Meeting on September 6-7, 2007 was attended by users from 12 ACTOR
sites and members of the Rigaku ACTOR team, ActiveSight and OSS.
To date, there
are 42 ACTOR installations worldwide, representing the highest number of sample
mounting robots from all commercial, government and academic endeavors
combined.
The success of the ACTOR system results from the
flexibility for integration, many software advancements, and a continued
commitment for development. In keeping with this spirit, the goal of the meeting
was to facilitate free discussion among ACTOR users and with the Rigaku ACTOR
team to identify bottlenecks, common user problems, and directions for future
development. The meeting included presentations from ACTOR users and open
discussion sessions.
The Rigaku ACTOR team also presented new hardware and
future development projects. An immediate outcome from the meeting included the
creation of a moderated e-mail list available to ACTOR users. Information will be
sent out in the coming week describing how ACTOR users can gain access to
meeting summaries, presentations, and the ACTOR user bulletin board. We thank
those who were able to attend the meeting this year for fruitful discussions and
hope to see all ACTOR users at future meetings.
