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. Phosphoserine antibody inhibitor may be used for the specific inhibition of the reactivity of anti-phosphoserine antibodies but not that of anti-phosphothreonine- or anti-phosphotyrosine-specific antibodies.
Specificity
O-phospho-L-serine conjugated to bovine serum albumin. Phosphoserine antibody inhibitor specifically blocks the reactivity of anti-phosphoserine antibody. It does not block the activity of anti-phosphothreonine or anti-phosphotyrosine-specific antibodies. The product is useful in immunoblotting and in ELISA.
Working dilution is at least 2 μg/ml by the specific inhibition of the reactivity of Monoclonal Anti-Phosphoserine (Sigma Product No. P3430), used in immunoblotting of rat cerebral cortex extract, and in ELISA.

Application
Phosphoserine-BSA may be used for specific inhibition of monoclonal anti-phosphoserine (Sigma Product No. P3430) in immunoblotting and ELISA applications, at a working dilution of 2 μg/mL.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

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

Protein phosphorylation plays a vital role in the regulation of most aspects of cellular activity, being key to propagating messages within signal transduction pathways and to modulating protein function. Pro-Q Diamond phosphoprotein gel stain is suitable for the fluorescence detection

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
