Extra Details:: Glycogen synthase kinase-3 (GSK-3), a multifunctional serine/threonine kinase, is a key regulator of numerous signaling pathways. Two isoforms of GSK-3 are reported in mammals: a 51kD GSK-3a and a 47kD GSK-3b. These two isoforms exhibit about 98% homology in their kinase domains, but share only about 36% identity in the last 76 C-terminal amino acid residues. GSK-3a contains a glycine-rich extension at its N-terminus. A minor (~15% of total) splice variant of GSK-3b, GSK-3b2, has also been identified, which contains a 13-residue insert within the kinase domain. It exhibits reduced kinase activity towards tau protein compared with ‘unspliced’ GSK-3b. GSK-3b2 is localized primarily to neuronal cell bodies, unlike unspliced GSK-3b that is also found in neuronal processes. GSK-3b plays a key inhibitory role in the Wnt signaling pathway. Wnt genes encode a large family of secreted, cysteine-rich proteins that are important in development and in maintenance of adult tissues. Abnormalities in Wnt signaling are reported to promote both human dgenerative diseases and cancer. Applications: Suitable for use in Western Blot and Immunocytochemistry. Not suitable for use in Immunoprecipitiation. Other applications not tested. Recommended Dilution: Western Blot: 0.5-2ug/ml. Detects GSK-3 in RIPA lysates from human Jurkat and A431, rat L6 and PC12 and mouse 3T3 cells. Jurkat cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with G8170-40 (0.5ug/ml). Proteins were visualized using an IgG (HRP) goat anti-mouse and a chemiluminescence detection system. Immunocytochemistry: 10ug/ml. Demonstrated positive immunostaining for GSK3 in L6 cells fixed with acetone. Optimal dilutions to be determined by the researcher. Positive Control (Included): J9000: Jurkat Cell Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
