Compounds and reagents used in this study. a Versatile reagents based on kinase inhibitors facilitates rapid generation of SNAPtag targeting kinase inhibitor and affinity matrices. KAM has been previously described by our group as compound 3. b Combinatorial library of ABL1 targeting SNAPtag-based bivalent inhibitors. Using SNAPtag as a universal linker, various specificity ligands and ATP-competitive ligands can be displayed from SNAPtag and used in combination to evaluate the influence of each component towards ABL1 binding
