PTPσ Inhibitor, ISP
Based on 1 Customer Validation
PTPσ Inhibitor, ISP can bind to recombinant human PTPs and inhibits PTPσ signaling. PTPσ Inhibitor, ISP can penetrate the membrane and relieves the chondroitin sulfate proteoglycan (CSPG)-mediated axonal sprouting inhibition in spinal cord injury model. PTPσ Inhibitor, ISP enhances remyelination in LPC-induced demyelinated spinal cord. PTPσ Inhibitor, ISP also promotes oligodendrocyte progenitor cells (OPCs) migration, maturation, remyelination, and functional recovery in animal models of Multiple Sclerosis (MS).
