Epitome Biosystems, PerkinElmer, Institute of Cancer Research, Sigma-Aldrich

Epitome Biosystems introduced this week the Ti-Tyr Phosphorylation Profiling Chip. The chips, which incorporate Epitome’s proprietary EpiTag technology, enable quick and specific cell-based measurements of biological function in a multiplexed format, the company said in a statement.

PerkinElmer this week launched its assay development service for advanced cellular science and drug discovery research. The service offers assay solutions for high-value G protein couple receptor and kinase cell-based screening, the company said in a statement. It also will provide miniaturization of tough-to-automate immunoassays.

The Institute of Cancer Research last week launched the Center for Bioinformatic and Clinical Proteins website, featuring a database of 4,244 human proteins, including many related to cancer.
The proteins in the database are restricted to SwissProt entries and currently focus on liver and colon cancers, melanoma, and various forms of leukemia. Breast and lung-cancer proteins will be included in the future.

Sigma-Aldrich launched its newly designed web-based Enzyme Explorer this week. The website has redesigned product indices, new metabolic pathway charts and animations, and in-depth technical monographs. Customers can also access interactive tools such as the Protease Finder and BioFiles issues, the company said in a statement.
