Monoclonal Mouse Affinity Purified B IP
Protein tyrosine phosphorylation has been the subject of intense investigation for over two decades. Tyrosine phosphorylation is catalyzed by members of the tyrosine kinase superfamily. To date, approximately 90 members of this superfamily have been identified in the human genome. Levels of phosphorylation of tyrosine residues within cellular proteins are observed to increase in response to growth factors, cytokines, insulin, extracellular matrix components, and other stimuli. Tyrosine phosphorylation has several effects, including the regulation of enzyme activity, as well as the localization of enzyme activity through the generation of docking sites for proteins bearing SH2 domains.
Catalog #P4078-28
ApplicationsSuitable for use in Western Blotting. Other applications not tested. For use in applications in which an HRP conjugate is advantageous, such as Western Blot and Immunoprecipitation .
Western Blotting 0.5-2ug/ml, with optimal performance at 2ug/ml (10ul per 10ml blocking
buffer). Detects tyrosine-phosphorylated proteins in RIPA lysates from EGF-treated human
A431 carcinoma cells. EGF-stimulated cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with anti-Phosphotyrosine, HRP conjugate (1ug/ml). Proteins were visualized using a chemiluminescence detection system.
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (30-50%). Freeze at -20°C. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Clone TypeMonoclonal
Clone No0.T.162
