Description

General description

Anti-Phosphotyrosine antibody, Mouse monoclonal (mouse IgG2b isotype) is derived from the pT-154 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a tyrosine phosphorylated peptide. Members of protein-tyrosine kinases (PTKs) family consists of extra-cellular domain that is responsible for ligand binding, a trans-membrane domain, modular domain and an intracellular domain.

Immunogen

tyrosine phosphorylated peptide.

Application

Anti-Phosphotyrosine antibody, Mouse monoclonal has been used in:

• enzyme linked immunosorbent assay (ELISA)
• western blot
• immunohistochemistry

Biochem/physiol Actions

Protein phosphorylation is a post-translational modification that regulates signal transduction. Phosphorylation of tyrosine residues in proteins has been associated with oncogenesis, cell growth and survival . Monoclonal Anti-Phosphotyrosine antibody is specific for rat and human proteins/peptides that contain phosphotyrosine residues. As determined by competitive ELISA, the product does not bind to non-phosphorylated tyrosine, phosphorylated serine or threonine, ATP or AMP.

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. They are tightly regulated by other kinases and by autophosphorylation activity. Monoclonal antibodies specific for phosphotyrosine are essential tools for the study of tyrosine phosphorylation in post-translational modification in many biological processes.

Physical form

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