p-EGFR抗体(12A3)是一种IgG1小鼠单克隆p-EGFR抗体,可通过WB和IP检测小鼠、大鼠和人源Tyr 845磷酸化的EGFR。p-EGFR抗体(12A3)可作为非偶联抗p-EGFR抗体形式提供。表皮生长因子通过与指定为EGFR(表皮生长因子受体)的细胞表面糖蛋白的相互作用来调节它们对细胞生长的影响。EGF或TGFα与EGFR的结合激活了EGFR固有的酪氨酸特异性蛋白激酶活性。EGFR上的羧基末端酪氨酸残基Tyr 1092和Tyr 1173(在大鼠中指定为Tyr 1196)是发生自磷酸化的主要位点,这是由EGF结合引起的。一旦被激活,EGFR通过直接与人和小鼠中的Tyr 1092和Tyr 1110或大鼠中的Tyr 1109相互作用,并通过与Ras信号通路中的Tyr 1173间接相互作用,介导GRB2的磷酸酪氨酸结合(PTB)域的结合。EGFR的Tyr 1173也作为激酶底物起作用。Tyr 992、Tyr 1092和Tyr 1110的磷酸化是EGFR C端尾部构象变化所必需的。Tyr 1092、Tyr 1173和Tyr 1110也分别指定为Tyr 1068、Tyr 1197和Tyr 1086。

At what dilution should the antibody be used for a western blot (in 5% non-fat dry milk/TBST) ?

Asked by: MmeSprits
Thank you for your question. The recommended starting dilution for this antibody is 1:100 for Western blot applications.

Is p-EGFR (12A3): sc-57542 monoclonal antibody specific for the phosphorylated protein, and will not cross-react with the non-phosphorylated form of the protein?

Asked by: jerojero
Yes, p-EGFR (12A3): sc-57542 is specific for p-EGFR phosphorylated at Tyrosine 845. The antibody has been validated through a series Western blot experiments using stimulated, non-stimulated and pervanadate treated lysates to demonstrate phospho-specificity.
