Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

Phospho-FAK (Tyr397) Antibody detects endogenous levels of FAK only when phosphorylated at Tyr397. This antibody may cross-react with overexpressed tyrosine phosphorylated EGF receptors.

磷酸化FAK (Tyr397)抗体仅仅在酪氨酸397磷酸化时检测内源性总的FAK水平,此抗体可能与过表达的酪氨酸磷酸化EGF受体交叉反应。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr397 of human FAK. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from NIH/3T3 cells, untransfected or transfected with activated Src, using Phospho-FAK (Tyr397) Antibody (upper) or FAK Antibody #3285 (lower).未转染或转染了激活Src的NIH/3T3细胞提取物,使用Phospho-FAK (Tyr397)抗体(上)或FAK抗体#3285(下)进行western blot分析。


Focal adhesion kinase (FAK) is a widely expressed cytoplasmic protein tyrosine kinase involved in integrin-mediated signal transduction. It plays an important role in the control of several biological processes, including cell spreading, migration, and survival (1). Activation of FAK by integrin clustering leads to autophosphorylation at Tyr397, which is a binding site for the Src family kinases PI3K and PLCγ (2-5). Recruitment of Src family kinases results in the phosphorylation of Tyr407, Tyr576, and Tyr577 in the catalytic domain, and Tyr871 and Tyr925 in the carboxy-terminal region of FAK (6,7).

黏着斑激酶(FAK)是一类广泛表达在细胞质的蛋白酪氨酸激酶,涉及整合素调节的信号转导,它起着重要的作用,在控制包括细胞扩散迁移和存活的一系列生物过程(1)。整合素成簇激活FAK,导致酪氨酸397的自磷酸化,这是一个Src家族激酶PI3K和PLCγ的结合位点(2-5). Src家族激酶的招募导致Tyr407, Tyr576和 Tyr577在催化结构域的磷酸化,以及Tyr871和Tyr925在FAK羧基末端区域的磷酸化(6,7)。
