KN-93 phosphate (Cat.No:I002455) is a cell-permeable and water-soluble analog of KN-93, a potent inhibitor of Ca²⁺/calmodulin-dependent protein kinase II (CaMKII). By blocking the activity of CaMKII, KN-93 phosphate interferes with various cellular processes and signaling pathways. It is commonly used in scientific research to study the functional roles of CaMKII in cellular physiology and pathology.
