phospho-Tyrosine Mouse anti-Human, Mouse, Clone: pY20, eBioscience
Mouse Monoclonal Antibody
Manufacturer: Invitrogen 14500182
Description: The pY20 monoclonal antibody recognizes phosphorylated tyrosine residues (p-Tyr) on proteins. Numerous intracellular signaling cascades are propagated via phosphorylation of specific tyrosine on signaling proteins. The detection of p-Tyr residues is valuable for the characterization and purification of phosphorylated proteins and the biochemical pathways that they are involved in. Applications Reported: This pY20 antibody has been reported for use in flow cytometric analysis, immunoprecipitation, and western blotting. Applications Tested: This pY20 antibody has been tested by immunoblotting of mouse spleen cells left untreated or treated with the phosphatase inhibitor sodium orthovanadate. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered.The role of tyrosine phosphorylation in transduction of the mitogenic signal from transmembrane receptors and in transformation by oncogene tyrosine kinases has been the subject of intense investigation for several years. While the phosphorylation of specific tyrosine residues has been shown to be a primary mechanism of signal transduction during normal mitogenesis, cell cycle progression and oncogenic transformation, its role in other areas such as differentiation and gap junction communication, is a matter of active and ongoing research. Antibodies that specifically recognize phosphorylated tyrosine residues have proved to be invaluable to the study of tyrosine -phosphorylated proteins and the biochemical pathways in which they function. The fluorescein (FITC) conjugate of clone PY20 anti-phosphotyrosine is especially useful for the detection of these P-Tyr proteins in immunohistochemical and immunocytochemical protocols in situations wherein the use of a secondary antibody would complicate detection of the protein(s) of interest.
