Congratulations to Dr. Christopher Gregg on winning the 2010 Eppendorf

& Science Prize for his studies on genes that alter their expression in the

brains of offspring according to whether they were inherited from the

father versus the mother. His findings suggest new pathways that may

help to understand brain diseases such as autism, schizophrenia and

eating disorders.

The annual international US$ 25,000 Eppendorf & Science Prize for

Neurobiology honors young scientists for their outstanding contributions

to neurobiological research based on methods of molecular and cell bio-

logy. The winner and finalists are selected by a committee of independent

scientists, chaired by Science’s Senior Editor, Dr. Peter Stern.

To be eligible, you must be 35 years of age or younger. If you’re selected

as this year’s winner, you will receive US$ 25,000, have your work

published in Science and be invited to visit Eppendorf in Hamburg,

Germany. Past winners and finalists have come from as far a field as

China, Chile, India and New Zealand. Yes, it can happen to you!

PARTICIPATING EXPERTS

During normal growth and differentiation,maintaining the appropriate homeostatic balance ina cell is paramount. This fundamental level of controlis achieved through the interaction of small moleculechemical modulators with those proteins involved incellular signaling. Researchers can take advantageof these regulatory interactions to study signalingpathways, for instance by designing chemicals thatreverse the hyper-proliferation phenotype seen inmany cancers. These small molecules can be usedboth as tools to interrogate a particular pathway andas precursors for drug development. This webinarwill provide an overview of how chemical biologycan be used in various model systems to bothadvance our understanding of basic cell signalingmechanisms as well as aid in the discovery of novelsmall molecule therapeutics for cancer.

During this webinar, the panelists will:• Provide an overview of how chemical biology can

impact cancer research

• Describe their own research using smallmolecules to elucidate signaling pathways andcharacterize their component proteins

• Give you the opportunity to ask them questions,live and in real time.

CELL COUNTER Designed for laboratories that routinely work with cells tagged with a large

variety of fl uorescent labels, the new Cellometer Vision allows users to easily

change out either of the two fl uorescence optics modules in the instrument

and replace it with another one. This enables scientists to perform experiments

using their choice of fl uorescent labels, with a broad spectrum of excitation and

emission wavelengths from ultraviolet to red. Using proprietary patent-pending

image processing and data analysis algorithms, Cellometer Vision combines

brightfi eld microscopy and one or two fl uorescence colors to count and analyze

cells that are loaded into a disposable chamber. A wide variety of fl uorescent

dyes may be used to stain the cells, providing clear declustering of the cells to

generate reliable viability results.

LIVER MICROSOMES A comprehensive range of liver microsome products from over 12

species, including mouse, rabbit, monkey, and chicken is now avail-

able. Researchers can select from pure microsomes or S9 fractions,

or animal liver cytosol. In order to facilitate requirements recom-

mended by REACH, bespoke microsome products from other spe-

cies or strains can also be supplied. Microsomes are a valuable tool

for investigating drug metabolism and examining in vitro drug-drug

interactions. They are produced by mechanically homogenizing cells

to fragment the endoplasmic reticulum, the fractions of which reform

into microsomes and are collected via differential centrifugation. Dur-

ing this process, the numerous different phase I cytochrome P450

enzymes are concentrated within the microsomes. The S9 fraction

contains microsomes as well as cytosolic phase II metabolism-relat-

ed enzymes.

CLOUD COMPUTING FieldAlign V3.0 is the latest in Cresset’s new generation of cloud-en-

abled applications, which support parallel, distributed computing by

default. It can be deployed both as a traditional desktop application

and as a command-line application distributed onto large computing

servers. FieldAlign is a powerful molecular design and 3D structure-

activity relationship (SAR) tool that generates biologically relevant

molecular comparisons, which can be used to fi nd the root causes of

activity or inactivity. FieldAlign helps chemists to gain detailed under-

standing of the SAR of their lead molecules and to use this to design

the best next synthesis. FieldAlign V3.0 introduces a range of user

features that improve productivity and customizability. Its command

line interface supports scripting and workfl ow systems, and is now

available on Windows, Linux, and Mac platforms. It incorporates a

new molecule table enabling fi ltering and sorting of lead molecules,

using imported data or standard physical properties such as wcLogP,

TPSA, and Rule of Five violations.

RNA, DNA, AND PROTEIN ISOLATIONTri-Xtract is a convenient, ready-to-use reagent designed for the iso-

lation of total RNA, DNA, and protein. Tri-Xtract is suitable for the

isolation of total RNA from small quantities of tissues and cells from

human, animal, plant, yeast, bacterial, and viral origin. Tri-Xtract is

a monophasic solution of phenol and guanidine thiocyanate that

maintains the integrity of the RNA during cell disruption and homog-

enization. The isolation procedure takes less than an hour and the

isolated RNA is suitable for Northern blots, dot blot hybridization, in

vitro translation, RNase protection assays, and poly (A+) selection.

FULL-LENGTH HUMAN PROTEINSThe new range of over 4,000 full-length, affi nity-purifi ed human

proteins, which are expressed in HEK293 cells and derived using

an extensive collection of human cDNA clones, is currently the

broadest offering of human proteins produced in human cells. It has

been prepared to ensure optimal preservation of protein structure,

posttranslational modifi cations, and function. All full-length proteins

come affi nity purifi ed and are guaranteed to be greater than 80%

pure, making them ideal for use as native antigens for optimized

antibody production, positive controls in antibody assays, enzyme-

linked immunosorbent assay standards, protein-protein interaction

experiments, in vitro biochemical assays, cell-based functional as-

says, and SRM/MRM standards. All the human proteins in the new

range are available in small trial-size quantities, which can be quickly

developed into larger (milligram) quantities.

FREEZE-DRYER AND LYOPHILIZATION SYSTEMThe latest freeze-drying and lyophilization innovation for improving

process control and minimizing issues of scale-up, the LyoStar 3, is

confi gured with the most innovative controls and instrumentation,

including Smart Freeze-Dryer Technology and Praxair’s ControLyo On

Demand Nucleation Technology. The LyoStar 3 is the ultimate lab-

scale system for formulations studies, process optimization, and

scale-up work. The system is a freeze-dryer that provides unmatched

process accuracy, reliability, and unique ease-of-use features. Until

now, the freezing step of lyophilization was uncontrolled due to the

random nature of the nucleation or crystal-forming process. Using

ControLyo technology on the LyoStar 3 now makes nucleation con-

trol a reality by regulating the nucleation temperature to within 1°C

of its freezing point. The results are improved product uniformity,

quality, and yield.
