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 Mouse Anti-Phospho-Tyrosine Monoclonal Antibody (Catalog # MAB1676), followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Tyrosine-phosphorylated proteins were detected (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 10.
Detection of Human Phospho-Tyrosine by Simple WesternTM. Simple Western lane view shows lysates of HUVEC human umbilical vein endothelial cells untreated (-) or treated (+) with 50 µM Pervanadate (PV) for 15 minutes, loaded at 0.2 mg/mL. Tyrosine-phosphorylated proteins were detected (as indicated) using 50 µg/mL of Mouse Anti-Phospho-Tyrosine Monoclonal Antibody (Catalog # MAB1676). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
Phospho-Tyrosine in A431 Human Cell Line. Phospho-Tyrosine was detected in immersion fixed A431 human epithelial carcinoma cell line treated with 50 ng/mL Recombinant Human EGF (left panel; Catalog # 236-EG) or untreated (right panel) using Mouse Anti-Phospho-Tyrosine Monoclonal Antibody (Catalog # MAB1676) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Tyrosine phosphorylation is considered to be one of the key steps in signal transduction and regulation of enzymatic activity. The phosphorylation of specific tyrosine residues has been shown to be a primary mechanism of signal transduction during normal cell cycle progression and oncogenic transformation. The role of tyrosine phosphorylation is a matter of active and ongoing research. Specific antibodies that recognize phosphorylated tyrosine residues are valuable to the study of tyrosine phosphorylated proteins and the biochemical pathways in which they are involved.
