General description
The activity of proteins depends on phosphorylation of specific amino acid residues. In applications involving identification of activated cellular proteins, it is important to confirm specificity of antibodies used against a particular phosphorylated amino acid. For such applications, inhibitors of phosphorylated antibodies on specific amino acid residues are suitable. Phosphotyrosine antibody inhibitor may be used for the specific inhibition of the reactivity of anti-phosphotyrosine antibodies but not that of anti-phosphothreonine- or anti-phosphoserine-specific antibodies.
Specificity
Phosphotyrosine antibody inhibitor that specifically blocks the reactivity of anti-phosphotyrosine antibody. It does not block the activity of anti-phosphothreonine or anti-phosphoserine-specific antibodies.
Application
Phosphotyrosine-BSA may be used for specific inhibition of phosphotyrosine in platelet extracts, in immunoblotting and ELISA applications, at a working concentration of 5 μg/mL.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Analysis Note
O-Phospho-L-tyrosine conjugated to bovine serum albumin

Paxillin has been recognized as a focal adhesion adapter protein that participates in the integrin-mediated signaling. An earlier study [Ogawa et al. Biochim. Biophys. Acta 1519 (2001) 235] found that frog paxillin was expressed in the kidney epithelial cell line

Topoisomerase II (Top2) activity involves an intermediate in which the topoisomerase is covalently bound to a DNA double-strand break via a 5'-phosphotyrosyl bond. Although these intermediates are normally transient, they can be stabilized by antitumor agents that act as Top2

Proliferating cells, including cancer cells, require altered metabolism to efficiently incorporate nutrients such as glucose into biomass. The M2 isoform of pyruvate kinase (PKM2) promotes the metabolism of glucose by aerobic glycolysis and contributes to anabolic metabolism. Paradoxically, decreased pyruvate
