Antibody Host Species: Rabbit

Antibody Immunogen Source: Human G6PD sequence peptide Cat. No.: PE-04ACV80
Antibody Immunogen Sequence: EAV(pY)TKM(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues E398 to M404; In the G6PD_C domain. One of the major in vivo phosphorylation sites in G6PD.

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: G6PD catalyzes the rate-limiting step of the oxidative pentose-phosphate pathway, which represents a major route for the dissimilation of carbohydrates in addition to glycolysis. The main function of this enzyme is to provide reducing power (NADPH) and pentose phosphates for fatty acid and nucleic acid synthesis. The biochemical reaction catalyzed is: D-glucose 6-phosphate + NADP+ = 6-phospho-D-glucono-1,5-lactone + NADPH.
