GST fusion protein containing full length human SAPK2a/p38a (64kDa).
Catalog #S0096-28
Specificity Essentially identical in mammals (p38 MAPK) and yeast (HOG-1). Inhibitors include protein phosphatase 2A, PTP-1B, CL-100 and pyridinyl imidazols.
Specific Activity 50units/mg using MBP as a substrate. One unit of SAPK2a/p38a = 1 nmol phosphate incorporated into MBP per minute.
SAPK2a Kinase Assay SAPK2a/p38a phosphorylated MBP.
