Specific src isoform is unknown

Src (also known as pp60src) is a non receptor Tyrosine Kinase involved in signal transduction in many biological systems and implicated in the development of human tumors. There are two critical phosphorylation sites of tyrosine on Src, tyrosine 418 and tyrosine 529 (referring to human Src sequence). The tyrosine 418 is located in the catalytic domain and is one of the autophosphorylation sites. Full catalytic activity of Src requires phosphorylation of tyrosine 418. This region of Src is also highly conserved in all of the related Src-family kinases, and thus prior immunoprecipitation may be required to identify which Src family member is being activated.

Recognizes phospho-Src, Mr 60kDa. The antibody does not crossreact with the nonphosphorylated form of Src or with unrelated phosphorylation sites. Predicted to recognize all Src family members phosphorylated at the tyrosine corresponding to Tyr416 of avian Src.

KLH-conjugated, synthetic peptide containing phosphotyrosine in the sequence context corresponding to tyrosine 416 of avian Src. Clone 9A6.

Detect phospho-Src (Tyr416) using this Anti-phospho-Src (Tyr416) Antibody, clone 9A6 validated for use in WB & IP.

Immunoprecipitation/Immunoblot Analysis: 4 μg/mL of a previous lot detected phospho-Src immunoprecipitated from 3T3 cell lysates with 10 μg of anti-Src (Catalog # 05-184), but not after phosphatase treatment with YOP.

Evaluated by immunoprecipitating Src from 3T3 cell lysates with anti-Src (Catalog #05-184), but not after phosphatase treatment with YOP.

Src Autophosphorylation/Western Blotting Analysis: 0.5-2 μg/mL of this antibody strongly detected recombinant Src (Catalog # 14-326) after incubation with Mg/Mn/ATP. Phospho-specificity was confirmed by dephosphorylation of the Src protein with λ-phosphatase.
