The Phosphotyrosine ptp99a (Catalog #MBS803082) is an Antibody produced from Mouse and is intended for research purposes only. The product is available for immediate purchase. MyBioSource\'s Phosphotyrosine can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunoprecipitation (IP), Immunofluorescence (IF), Immunohistochemistry (IHC).
1:1000 (WB). Researchers should empirically determine the suitability of the Phosphotyrosine ptp99a for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process.

The Phosphotyrosine ptp99a product has the following accession number(s) (GI #157294) (NCBI Accession #AAA28483.1). Researchers may be interested in using Bioinformatics databases such as those available at The National Center for Biotechnology Information (NCBI) website for more information about accession numbers and the proteins they represent. Even researchers unfamiliar with bioinformatics databases will find the NCBI databases to be quite user friendly and useful.

Please refer to the product datasheet for known applications of a given antibody. We\'ve tested the Phosphotyrosine Antibody: PerCP with the following immunoassay(s):
Immunohistochemistry (IHC) (Immunohistochemistry analysis using Mouse Anti-Phosphotyrosine Monoclonal Antibody, Clone G104. Tissue: backskin. Species: Mouse. Fixation: Bouin\'s Fixative and paraffin-embedded. Primary Antibody: Mouse Anti-Phosphotyrosine Monoclonal Antibody at 1:100 for 1 hour at RT. Secondary Antibody: FITC Goat Anti-Mouse (green) at 1:50 for 1 hour at RT. Localization: Stratum granulosum staining in the epidermis. Some dermal staining.)
Immunohistochemistry (IHC) Phosphotyrosine.

Western Blot (WB) (Western Blot analysis of Human A431 cell lysates showing detection of Phosphotyrosine protein using Mouse Anti-Phosphotyrosine Monoclonal Antibody, Clone G104. Load: 15 ug. Block: 1.5% BSA for 30 minutes at RT. Primary Antibody: Mouse Anti-Phosphotyrosine Monoclonal Antibody at 1:1000 for 2 hours at RT. Secondary Antibody: Sheep Anti-Mouse IgG: HRP for 1 hour at RT. Left: normal, right: EGF treated.)
Western Blot (WB) Phosphotyrosine.

Background Info: Reacts with phosphotyrosine, and detects the presence of phosphotyrosine in both un-stimulated and stimulated cell lysates. Does not cross-react with phosphoserine or phosphothreonine.

Scientific Background: Protein phosphorylation is an important posttranslational modification that serves many key functions to regulate a protein\'s activity, localization, and protein-protein interactions. Phosphorylation is catalyzed by various specific protein kinases, which involves removing a phosphate group from ATP and covalently attaching it to to a recipient protein that acts as a substrate. Most kinases act on both serine and threonine; others act on tyrosine, and a number (dual specificity kinases) act on all three. Because phosphorylation can occur at multiple sites on any given protein, it can therefore change the function or localization of that protein at any time (3). Changing the function of these proteins has been linked to a number of diseases, including cancer, diabetes, heart disease, inflammation and neurological disorders (4-6). In particular, the phosphorylation of tyrosine is considered one of the key steps in signal transduction and regulation of enzymatic activity (7). Phosphotyrosine can be detected through specific antibodies, and are helpful in facilitating the identification of tyrosine kinase substrates (8).

Conjugate: PerCP. Storage Buffer: PBS pH7.4, 50% glycerol, 0.09% sodium azide.
