Milli-Mark^® Anti-Phosphotyrosine-PE Antibody, recombinant clone 4G10^®

Dependent upon the molecular weight of the tyrosine phosphorylated protein being detected.

Some of the tyrosine residues can be tagged with a phosphate group by protein kinases and 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 the significant events in signal transduction research. Before the availability of anti-phosphotyrosine antibodies, tyrosine phosphorylation 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 tyrosyne 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.
