The Comprehensive Kinase Screening Library consists of 11 plates and contains more than 850 selective and non-selective kinase inhibitors in a 96-well Matrix• tube rack format as 10 mM stock solutions in DMSO. This comprehensive library includes inhibitors of a wide range of lipid, receptor and non-receptor tyrosine, serine/threonine, and dual specificity kinases including those belonging to ROCK, activin-like kinase (ALK), GSK3, PKC, PDGFR, VEGFR, Src, MAPK, CDK, and PI3K families, among many others. It has greater coverage of individual kinases, kinase isoforms and mutants, and kinase families compared to 's Kinase Screening Library .
