General description

Anti-Phosphotyrosine antibody (05-321), cross-linked to horseradish peroxidase
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-phospho-tyrosine 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 response to various treatments.

Description
IgG2bκ mouse monoclonal antibody produced in vitro by mouse-mouse hybridoma 4G10. Purified by Protein G-Sepharose chromatography and cross-linked to horseradish peroxidase.

Specificity

Quality

Routinely evaluated in western blot on RIPA lysates from EGF-treated human A431 carcinoma cells.

Western Blot Analysis:
Tested at 0.5-2 μg/mL, with optimal performance at 2 μg/mL (10 μL per 10 mL blocking buffer). This lot detected tyrosine-phosphorylated proteins in RIPA lysates from EGF-treated human A431 carcinoma cells.

Target description

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

Physical form

200 μg of IgG2bκ-HRP conjugate in 100 μL PBS containing 0.05% Kathon® . Sufficient for 10 western blots, if used at the optimum concentration of 2 μg/mL in 10 mL blocking buffer. Liquid.
Protein G-Sepharose Chromatography
