Specificity
Clone 6K18 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects GSK-3b phosphorylated on serine 9.
Immunogen
KLH-conjugated linear peptide corresponding to 9 amino acids surrounding phosphoserine 9 in human GSK-3b.
Application
Quality Control Testing
Evaluated by Western Blotting in lysate from HeLa cells treated with phorbol 12-myristate 13-acetate (PMA).
Western Blotting Analysis (WB): A 1:10,000 dilution of this antibody detected GSK-3β phosphorylated on serine 9 in lysate from HeLa cells treated with phorbol 12-myristate 13-acetate (PMA; 500 nM; 30 min).
Tested applications
Western Blotting Analysis: A 1:10,000 dilution from a representative lot detected phospho-GSK3β Ser9 in lysate from NIH3T3 cells treated with PDGF.
Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected phospho-GSK3β-Ser9 in HeLa cells treated with phorbol 12-myristate 13-acetate (PMA)..
Peptide Inhibition Assay: Target band detection in lysate from HeLa cell treated with phorbol 12-myristate 13-acetate m(PMA) was prevented by preblocking of a representative lot with the immunogen phosphopeptide, but not the corresponding non-phosphopeptide.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Target description
Glycogen synthase kinase-3 beta (UniProt: P49841; also known as EC:2.7.11.26, GSK-3 beta, Serine/threonine-protein kinase GSK3B) is encoded by the GSK3B gene (Gene ID: 2932) in human. GSK-3 is a multifunctional serine/threonine kinase, is a key regulator of numerous signaling pathways during embryogenesis and in metabolic control. Two isoforms of GSK-3 are reported in mammals: a 51 kDa GSK-3a and a 47 kDa 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-terminal. GSK-3 is constitutively active in cells and is regulated through inhibition of its activity. It shows a preference for target proteins that are pre-phosphorylated at a priming residue located C-terminal to the site of GSK-3 phosphorylation. Priming phosphorylation, although not absolutely required, enhances the efficiency of phosphorylation of most GSK-3 substrates. Phosphorylation of a threonine residue in the activation loop (T-loop) is considered to be essential for its activity. The T-loop of GSK-3a is phosphorylated at Tyr279 and GSK-3b at Tyr216, which play a role in forcing open the substrate-binding site of the enzyme. A primary mechanism of GSK3 activity regulation is phosphorylation of N-terminal serine residues (Serine 21 in GSK-3a and serine 9 in GSK-3b). Phosphorylation of these sites is inhibitory to GSK3 kinase activity because the phosphorylated N-terminus acts as a competitive inhibitor for primed substrates. GSK-3b is constitutively active in resting cells and treatment of cells with an agent, such as insulin, causes GSK-3 inactivation through a PI 3-kinase (PI 3-K)-dependent mechanism. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
Reconstitution
300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
Storage and Stability
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
