Antibody Code: PN516

Antibody Target Type: Phosphosite-specific

Antibody Phosphosite: Y406

Protein UniProt: Q13480

Protein SigNET: Q13480

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human Gab1 sequence peptide Cat. No.: PE-04ACW80
Antibody Immunogen Sequence: QDC(pY)DIP(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues Q403 to P409; In the mid-region of the protein. This is the second major in vivo phosphorylation site of Gab1. Effect of phosphorylation is unclear.

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: Gab1 is an adapter protein that plays a role in intracellular signalling cascades triggered by activated receptor-type kinases. It plays a role in FGFR1 signalling and is probably involved in signalling from the epidermal growth factor receptor (EGFR) and the insulin receptor (INSR).
