Human MAP3K1 (XP_042066.8, 1327 a.a. - 1646 a.a.) partial recombinant protein with GST tag expressed in baculovirus infected Sf21 cells.
Theoretical MW (kDa):
Baculovirus infected insect cell (Sf21) expression system
Glutathione sepharose chromatography
82 % by SDS-PAGE/CBB staining
The activity was determined by ELISA. The enzyme was incubated with GST-fused substrate protein, and after stopping kinase reaction by EDTA, the reaction solution was transferred into glutathione-coated plate. Phosphorylation was detected by anti-phospho antibody and HRP-labeled anti-rabbit IgG (or HRP-labeled anti-mouse IgG). Substrate: MAP2K1 [inactive mutant]. ATP: 100 uM.
Quality Control Testing:
Loading 1 ug protein in SDS-PAGE
In 50 mM Tris-HCl, 150 mM NaCl, pH 7.5 (0.1% CHAPS, 1 mM DTT, 10% glycerol)
Store at -80°C. Aliquot to avoid repeated freezing and thawing.
MAP3K, or MEK kinase, is a serine/threonine kinase that occupies a pivotal role in a network of phosphorylating enzymes integrating cellular responses to a number of mitogenic and metabolic stimuli, including insulin (MIM 176730) and many growth factors.[supplied by OMIM
