Cell Signaling Technology (CST) provides the highest quality antibodies, reagents, and kits for in vitro and cell-based assays, to support any stage of the drug discovery process. CST is also the exclusive provider of XP® monoclonal antibodies, which offer superior sensitivity, specificity, and the most reproducible results. CST™ antibodies have been validated on multiple assay platforms by our in-house immunofluorescence group. PathScan® Multiplex kits allow simultaneous detection of key signaling pathway nodes using manual immunofluorescence microscopy, or automated imaging and laser scanning HCS platforms. As always, all CST products are technically supported by the same scientists who validate the products and know them best.
