Ordering Information

Biological Activity

KN-93 is a cell-permeable, competitive Ca2+/calmodulin-dependent protein kinase II (CaMKII) inhibitor with a Ki of. By disrupting CaMKII activation and downstream signaling pathways, KN-93 modulates cellular processes including calcium ion transport, cardiac excitation-contraction coupling, neuronal plasticity, and cell cycle progression. Inhibition of CaMKII by KN-93 suppresses substrate phosphorylation, leading to attenuated cell proliferation and altered intracellular calcium homeostasis. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
