ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

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. a multifunctional serine/threonine kinase, is a key regulator of numerous signaling pathways during embryogenesis and is involved in metabolic control. Two isoforms of GSK-3 are reported in mammals: a 51 kDa GSK-3α and a 47 kDa GSK-3β. 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. The GSK-3α 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-3α is phosphorylated at Tyr279 and GSK-3β 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-3α and serine 9 in GSK-3β). Phosphorylation of these sites is inhibitory to GSK3 kinase activity because the phosphorylated N-terminus acts as a competitive inhibitor for primed substrates.  GSK-3β 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.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
