Myelin Basic Protein, dephosphorylated
substrate for in vitro kinase assays
Myelin Basic Protein, MBP, is useful as a substrate for in vitro kinase assays, including MAPK, PKA, PKC cyclin-dependent and calmodulin-dependent protein kinases.

Myelin Basic Protein is purified from bovine brain using SP-Sepharose™ FPLC and dephosphorylated using lambda phosphatase. Lambda phosphatase is then inactivated by the addition of EDTA and heat treatment (65°C for 1 hour). The estimated purity is >95% based on Coomasie staining.
