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 in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™650 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
