K252B is a non-selective protein kinase inhibitor that targets CaMKII, MYLK, PKA, PKC, and cGKI by binding to the ATP-binding domain of these kinases. It is cell-permeable and used in neuroscience to study the regulation of intracellular signaling pathways involved in synaptic transmission, plasticity, and neuronal survival. K252B is particularly useful in dissecting the roles of calcium/calmodulin-dependent kinases and cyclic nucleotide-dependent kinases in neurodevelopment and neurodegeneration.

Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.
- Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
- Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
- Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
- QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
- Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity
To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
