Spezifität

Anti-Phosphotyrosine recognizes tyrosine phosphorylated proteins.

Immunogen

phospho-L-tyrosine conjugated to KLH

Anwendung

Anti-Phosphotyrosine antibody is suitable for use in indirect immunofluorescence (3-6 μg/mL using A431 stiμLated by human EGF) and immunoblot (using U2OS Dr1 cells ). The antibody may also be used for immunoprecipitation (1:40 using rat lumbar and thoracic lysates) and immunocytochemistry.

Biochem./physiol. Wirkung

Protein phosphorylation is the most abundant among post-translational modifications of cellular proteins, regulating intracellular signal transduction pathways in every living cell. Tyrosine, serine and threonine are the major amino acids that are phosphorylated in proteins. Antibodies specific for phosphotyrosine are essential tools for the characterization of tyrosine phosphorylation in many signal transduction pathways.

Physikalische Form

Solution in 0.01 M phosphate buffered saline, pH 7.4, and 1% BSA, containing 15 mM sodium azide.

Lagerung und Haltbarkeit

For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.

Dysregulated expression of epidermal growth factor receptor (EGFR) has been implicated in many cancer events, while peroxisome proliferator-activated receptor γ (PPARγ) negatively regulates cancer progression. The molecular mechanism of EGFR interaction with PPARγ is still unclear. Here, we found that
