Description
Catalogue Number	05-321
Replaces	MAB3090
Brand Family	Upstate
Trade Name	Upstate
Description	Anti-Phosphotyrosine Antibody, clone 4G10?
Background Information	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.

Product Information
Format	Purified
Control	Untreated A-431 (negative control) and EGF treated A-431 (positive control) whole cell lysates. Included Positive Antigen Control: Catalog # 12-302, EGF-stimulated A431 cell lysate is provided as a free positive antigen control for western immunoblotting. Aliquot as desired, refreeze immediay, and store at -20°C. The lysate is stable for 6 months at -20°C. Before use, add 2.5 μL of 2-mercaptoethanol/100 μL of lysate and boil for 5 minutes to reduce the preparation. Load 20 μg of reduced lysate per lane for immunoblot analysis.
Presentation	0.1M Tris-Glycine, 0.15M NaCl, 0.05% Sodium Azide, pH 7.4. Liquid at 2-8°C. IgG2bκ mouse monocolonal antibody produced in vitro by mouse-mouse hybridoma 4G10? (FOX-NY [NS-1 derivative] myeloma x spleen cells).

Applications
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
Key Applications	Immunocytochemistry Western Blotting Immunoprecipitation Immunohistochemistry
Application Notes	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.
