  WB analysis using 28875-1-AP

  Non-treated PC-3 and Calyculin A treated treated PC-3 cells were subjected to SDS PAGE followed by western blot with 28875-1-AP (Phospho-GSK3A (Ser21) antibody) at dilution of 1:3000 incubated at 4℃ overnight. The membrane was stripped and re-blotted with GAPDH antibody as loading control.

Tested Applications

• Positive WB detected in: Calyculin A treated PC-3 cells

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:6000

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

GSK3A (glycogen synthase kinase 3 alpha), one of the two functional isoforms encoded by the GSK3 gene, is a serine/threonine protein kinase that is involved in cell-cycle progression, differentiation, and apoptosis (PMID: 27049759). Glycogen synthase kinase-3 (GSK-3) was initially identified as an enzyme that regulates glycogen synthesis in response to insulin.GSK-3 is a critical downstream element of the PI3K/Akt cell survival pathway whose activity can be inhibited by Akt-mediated phosphorylation at Ser21 of GSK-3A and Ser9 of GSK-3B. GSK3A acts as a tumor suppressor and has important roles in acute myeloid leukemia (AML), prostate cancer, and pancreatic cancer (PMID: 22326953, 22539113, 23547054).
