Species predicted to react based on 100% sequence homology: Rat.磷酸化HER2/ErbB2 (Tyr877)抗体仅在Tyr877被磷酸化后才能检测到内源性ErbB2的存在。本抗体可能与其它酪氨酸位点磷酸化的ErbB家族蛋白(如EGFR)发生交叉反应。多克隆抗体通过用多肽免疫动物得到,该磷酸化多肽是根据人的ErbB2蛋白Tyr877附近的氨基酸序列合成的。抗体经过protein A和亲和层析纯化。Phospho-HER2/ErbB2 (Tyr877) Antibody detects endogenous levels of ErbB2 only when phosphorylated at tyrosine 877. The antibody may cross-react with other ErbB family members (e.g., EGF receptor) when phosphorylated at their tyrosine residues.Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr877 of human ErbB2. Antibodies are purified by protein A and peptide affinity chromatography.
