Anti-GSK3A (phospho S21) Antibody

This rabbit-derived polyclonal reagent targets GSK3A only when phosphorylated at serine 21, allowing researchers to distinguish the active kinase from its inhibited pool in cell signaling studies. Provided by Antibodies.com as a 200 µl unconjugated IgG preparation, the antibody is validated for Western blot, immunohistochemistry, and immunofluorescence workflows across human, mouse, and rat samples. Typical investigations include insulin and Wnt pathway dissection, neuronal survival assays, and tumor biology screens where S21 phosphorylation status acts as a functional readout. The reagent ships in liquid vial format and should be stored at -20 °C in working aliquots to limit freeze-thaw cycles, with brief refrigeration acceptable for short-term use. IgG isotype and unconjugated status make it compatible with both fluorescent and enzymatic secondary detection systems, supporting flexibility across imaging and blotting pipelines.
