This service allows the production of antibodies that will specifically recognize the phosphorylated state of your target protein. The approach includes the synthesis and purification of phosphorylated and non-phosphorylated peptides, immunisation, fabrication of two affinity columns for successive purification. Extensive ELISA on phospho-specific antibodies as well as on the fraction specific to the non-phosphorylated state is performed. We have successfully utilized this method with other post-translational modifications including acetylation and methylation.
