Press Release Summary: GenScript raises the quality standard for its antibody
packages.

Press Release Body: PISCATAWAY, N.J., Oct. 16, 2008 - International contract
research organization (CRO) GenScript Corporation has renewed the guarantees for its
custom antibody service packages. At present, GenScript guarantees positive Western
blot for polyclonal and monoclonal antibody generated from qualified protein antigen
and ELISA titer as high as 1:20000 or better for both standard and express
polyclonal antibody generated using peptide antigen designed, synthesized and
conjugated by GenScript.

GenScript guarantees the qualities of antibody for both of its polyclonal and
monoclonal antibody production. "The renewed guarantees represent our technological
advancement in antibody production." says Dr. Louis Liu, Director of the Antibody
Department from GenScript. "The positive Western blot result is among the highest
standard in the field. It makes GenScript stand out from its competitors." Many
other biotech company's antibody guarantees does not mention western blot results.

Dr. Liu claims that this is possible because of GenScript's OptimumAntigenTM Design
Tool, Nanotechnology for antigen preparation, and T-MaxTM Adjuvant. Specifically,
GenScript's OptimumAntigenTM Design Tool takes the peptides' length, antigenicity,
stability, cross-reactivity, terminus capping, and interactions with natural
biological activities into account during the design process. GenScript antigen
mixtures are processed down to nanoparticles to maximize immunization efficiency and
boost immune response. In addition, GenScript's T-MaxTM adjuvant is significantly
more potent in inducing the immune reaction than the standard Freund's adjuvant,
which ensures high specificity and high titer of the produced antibodies.

Based on our historical records, at least 96.4% of the orders for which peptide
antigens designed, synthesized and conjugated by GenScript received higher ELISA
titer (≥1:32,000) than guaranteed. This builds up the confidence for GenScript
to raise the bar of ELISA titer to 1:20000.

If the guarantee is unmet, GenScript will reinitiate the polyclonal antibody project
free of charge. Meanwhile, GenScript monoclonal antibody production guarantees two
positive clones for antibodies generated from both peptide antigen designed by
GenScript and high quality protein antigen. In all cases, if GenScript's guarantees
are unmet, GenScript will charge only set up fee for monoclonal antibody failures.

GenScript Corporation is a reliable outsourcing partner providing a wide array of
services to augment all stages of the drug discovery and biological reagent
manufacturing processes, including high-quality gene synthesis and cloning, custom
protein expression and purification, custom peptide synthesis and antibody
development, custom stable cell line development, and a wide selection of biological
reagents to life science researchers in industrial and academic settings. GenScript
Corporation is headquartered in Piscataway, New Jersey.
