Description

Immunogen

phosphoserine conjugated to Keyhole Limpet Hemocyanin (KLH).

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)

The antibody has been used for the detection of some phosphoserine containing proteins using immunoblotting and dot blotting.

Biochem/physiol Actions

By ELISA and dot blot, the antibody reacts specifically with phosphorylated serine, both as free amino acid or conjugated to carriers such as BSA or KLH. No cross-reactivity is observed with non-phosphorylated serine, phosphothreonine, phosphotyrosine, AMP or ATP. This antibody has been used in immunoblotting for the localization of some phosphoserine-containing proteins. Certain proteins known to contain phosphorylated serine may not be recognized by this antibody due to steric hindrance of the recognition site.

Protein phosphorylation and dephosphorylation are basic signaling mechanisms that modify protein function in eukaryotic cells. Phosphorylation is a rare posttranslational event in normal tissues, however, the abundance of phosphorylated cellular proteins increases several folds following various activation processes. The main amino acids that are phosphorylated are tyrosine, serine, or threonine (pTyr/pSer/pThr), each having specific kinases that phosphorylate them and specific phosphatases that dephosphorylate them. Mono and polyclonal antibodies directed against phosphorylated residues were generated and found useful as analytical and preparative tools by enabling the identification, quantification, and immunoaffinity isolation of phosphorylated cellular proteins.
