Scientific background

K252b is an alkaloid isolated from Nocardiopsis sp. soil fungi. It is a less potent derivative of K252a,3-5 cell-permeable protein kinase inhibitor.This compound potentiates neurotrophin-3 activity in certain neurons by an unknown mechanism. In other neurons it serves as a control to K252a since it accumulates in the plasma membrane of the neuron.1

Lead time: 1-2 Business Days

Country of origin: Israel/IL

Applications key

Application key: FC- Flow cytometry, IFC- Indirect flow cytometry, IHC- Immunohistochemistry,LCI- Live cell imaging, Calcium imaging assay,Cell survival assay, Electrophysiology, Neurite outgrowth assay.
