Spécificité

Clone 1E22 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects GSK-3a phosphorylated on serine 21.

Immunogène

KLH-conjugated linear peptide corresponding to 10 amino acids surrounding phosphoserine 21 from the N-terminal region of human GSK-3a .

Application

Quality Control Testing

Evaluated by Western Blotting in lysate from HEK293 cells treated with EGF.

Western Blotting Analysis: A 1:10,000 dilution of this antibody detected GSK-3a phosphorylated on serine 21 in lysate of HEK293 cells overnight starved and treated with epidermal growth factor (50 ng/mL; 10 min.).

Tested applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected phospho-GSK-3a-Ser21 in lysate from NIH3T3 cells treated with PDGF.

Peptide Inhibition Assay:: Target band detection in a lysate from HEK293 cells treated with epidermal growth factor (50 ng/mL; 10 min) was prevented by preblocking of a representative lot with the immunogen phosphopeptide, but not the corresponding non-phosphopeptide.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected phospho-GSK-3a-Ser21 in human breast cancer tissue sections.

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected phospho-GSK-3a-Ser21 in Hek293 treated with EGF cell line.

Flow Cytometry Analysis: 0.1 μg from a representative lot detected phospho-GSK-3a-Ser21 in HEK293 cells treated with EGF.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Description de la cible

Glycogen synthase kinase-3 alpha (UniProt: P49840; also known as EC:2.7.11.26, GSK-3 alpha, Serine/threonine-protein kinase GSK3A) is encoded by the GSK3A gene (Gene ID: 2931) 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. It 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. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forme physique

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.

Stockage et stabilité

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.
