Glycogen Synthase Kinase-3 differs from most serine/threonine kinases because it is active during the absence of activated signaling pathways. Two isoforms exist, GSK-3a and GSK-3b. GSK-3 phosphorylate glycogen synthase and thereby inactivate it. Insulin action stimulates the PI 3-kinase pathway, resulting in Ak activation, which phosphorylates and inactivates GSK-3.
Applications:
Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested.
Recommended Dilution:
Immunohistochemistry: 1:100 for 10min at RT
Staining of formalin-fixed tissues requires boiling tissues sections in 10mM citrate buffer, pH 6.0, for 10min followed by cooling at RT for 20min
Optimal dilutions to be determined by the researcher.
Positive Control:
Jurkat cells, brain
