Biochem/physiol Actions

Protein phosphorylation is a basic signaling mechanism that modifies protein function in eukaryotic cells. Serine, threonine, and tyrosine are the major phosphorylated amino acids in proteins. Tyrosine phosphorylation is a rare post-translational event in normal tissues, accounting for only 0.03% of phosphorylated amino acids. However, this phosphorylation increases several folds by various activation signals and the process is mediated by protein tyrosine kinases. Protein-tyrosine kinases (PTKs) are enzymes that catalyze the transfer of γ-phosphate of ATP to tyrosine residues of protein substrates. The PTKs are responsible for many biological processes like cell cycle, proliferation, oncogenesis, and development.

General description

As determined by ELISA and competitive ELISA, the antibody reacts specifically with phosphorylated tyrosine, both as free amino acid or conjugated to carriers such as BSA or KLH. No cross-reactivity is observed with non-phosphorylated tyrosine, phosphothreonine, phosphoserine, AMP or ATP.

Monoclonal Anti-Phosphotyrosine (mouse IgG1 isotype) is derived from the PT-66 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with phosphotyrosine-BSA conjugate.

Immunogen

phosphotyrosine conjugated to BSA

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Specificity

Monoclonal Anti-Phosphotyrosine is specific for phosphorylated tyrosine both as the free amino acid or when conjugated to carriers such as BSA or KLH. It does not react with non-phosphorylated tyrosine or other phosphorylated amino acids, including serine
