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: PCYT1A is the rate limiting enzyme in the biosynthetic pathway for phosphatidylcholine. It catalyzes the reaction: CTP + phosphocholine = diphosphate + CDP-choline. It is an ambiquitous enzyme that resides in the cytoplasm of cells in an inactive form. Diacylglycerol, acidic phospholipids and fatty acids drive the binding of PCYT1A to the endoplasmic reticulum and stimulation of its catalytic activity.
