PP1 (CAT: I002248) is a potent and selective inhibitor of protein tyrosine kinases (PTKs). It is commonly used in research to investigate the function and signaling pathways of specific PTKs. PP1 has been employed in various studies to elucidate the roles of specific kinases in cellular processes and to evaluate their therapeutic potential.
