Description
Each antibody in the SignalStain® Phospho-ErbB Family IHC Sampler Kit detects endogenous levels of its target protein. Phospho-EGF Receptor (Tyr1068) (D7A5) XP® Rabbit mAb detects endogenous EGF receptor only when phosphorylated at Tyr1068. This antibody may cross-react weakly with other tyrosine-phosphorylated proteins. Phospho-HER2/ErbB2 (Tyr1221/1222) (6B12) Rabbit mAb detects endogenous levels of ErbB2 only when phosphorylated at Tyr1221/1222. The antibody does not cross react with other activated ErbB family members or other tyrosine-phosphorylated proteins. Phopho-HER3/ErbB3 (Tyr1289) (D1B5) Rabbit mAb detects endogenous levels of HER3/ErbB3 proteins only when phosphorylated at tyrosine 1289. The antibody does not cross-react with other phosphorylated receptor tyrosine kinases at significant level. EGF Receptor (D38B1) Rabbit mAb detects endogenous levels of total EGF receptor protein
