Detects proteins containing phosphorylated tyrosine residues in Western blots. In Western blots of pervanadate-treated cell lysates, clone 216954 binds Phospho-Tyrosine in a broad manner largely independent of the surrounding amino acid sequence. No cross-reactivity with proteins or peptides containing phosphorylated serine or threonine residues is observed.

Scientific Data Images for Phospho-Tyrosine Antibody

Detection of Phospho-Tyrosine by Western Blot.

Western blot shows lysates of A431 human epithelial carcinoma cell line untreated (-) or treated (+) with 50 µM pervanadate (PV) for 15 minutes. PVDF membrane was probed with 1 µg/mL of Rat Anti-Phospho-Tyrosine Monoclonal Antibody (Catalog # MAB16761), followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). Tyrosine-phosphorylated proteins were detected (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 10.

Background: Phospho-Tyrosine

Phosphorylation of tyrosine residues in signaling proteins by protein tyrosine kinases mediates a variety of cellular processes, including cell growth, differentiation, adhesion, motility, death, and metabolism. Dysregulation of tyrosine phosphorylation has been implicated in the development of many human diseases, such as diabetes and cancer. Antibodies specific for phospho-tyrosine have been invaluable reagents in the studies of signaling pathways initiated by tyrosine phosphorylation.
