In the market-place

Finding the right reagent or assay for the job in hand can be a daunting prospect in a field as complex as cell signalling. Some companies are taking a one-stop shopping approach; others are pursuing niche markets, specializing in, for example, antibodies, peptide substrates for kinases and proteases, enzymes, especially protein kinases, or protein and peptide microarrays, such as those from Sigma-Aldrich in St Louis, Missouri, PepScan Systems in Lelystad, the Netherlands, and Zeptosens in Witterswil, Switzerland.
