General description
Some of the tyrosine residues can be tagged with a phosphate group (phosphorylated) by protein kinases. (In its phosphorylated state, it is referred to as phosphotyrosine.). Tyrosine phosphorylation is considered as one of the key steps in signal transduction and regulation of enzymatic activity.
The advent of anti-phosphotyrosine antibodies is one of significant events in signal transduction research. Before the availability of anti-phosphotyrosine antibodies, tyrosyl phospyhorylation of proteins and enzymes was investigated through hazardous and time-consuming radioactive experiments. Anti-phosphotyrosine antibodies are commonly used in western blots after the targeted proteins have been immunoprecipitated to measure the tyrosyl phosphorylation of the proteins. Anti-phosphotyrosine antibodies are also directly used on cell lysate to examine the overall change of tyrosine phosphorylation level in reponse to various treatments.

Specificity
This antibody recognizes tyrosine-phosphorylated proteins from all species.
Immunogen
Phosphotyramine-KLH
Application
Anti-Phosphotyrosine Antibody, clone 4G10 detects tyrosine phosphorylated proteins in all species. This unique monoclonal antibody is validated for use in IC, IH, IP, WB and is backed by hundreds of publications
Immunoprecipitation:
2-4 μg of a previous lot immunoprecipitated quantitatively the phosphotyrosine containing proteins in the lysate of a confluent culture (10 cm dish) of cells expressing an activated tyrosine kinase. To preserve phosphotyrosine, add: 0.2 mM sodium orthovanadate to the lysis buffer.
