Phosphorylation of specific tyrosine residues is an important post-translational modification for regulating the activity of most proteins. Stimulation of a variety of cell signaling pathways activates the receptor and non-receptor tyrosine kinases that mediate these protein modifications. Antibodies that can detect phosphotyrosine residues are excellent tools for characterizing changes in the post-translational state of a broad range of phosphotyrosine-containing proteins. Immunoprecipitation of proteins of interest, followed by detection of phosphotyrosine using anti-phosphotyrosine antibody is commonly used to correlate changes in tyrosine phosphorylation state with alterations in protein activity.

Western blot of HeLa cells treated with pervanadate (1 mM) for 30 min. Phosphotyrosine containing proteins were immunoprecipitated with rabbit polyclonal anti-Phosphotyrosine:Agarose (Lane 1) or with no antibody agarose beads (Lane 2), and blots were made that included the whole lysate (Lane 3). The blots were probed with mouse monoclonal anti-Phosphotyrosine (PM3751) to detect phosphotyrosine containing proteins.
Immunocytochemical labeling of phosphotyrosine in control and pervanadate-treated A431 cells. The cells were labeled with rabbit polyclonal anti-Phosphotyrosine (PP2221) and mouse monoclonal anti-Phosphotyrosine (PM3751), then the antibodies were detected using appropriate secondary antibodies conjugated to Cy3.
