Species predicted to react based on 100% sequence homology: Rat。HER3/ErbB3 (D22C5) XP® Rabbit mAb (Biotinylated) recognizes endogenous levels of total HER3/ErbB3 protein. This antibody does not cross-react with other HER family proteins.This Cell Signaling Technology antibody is conjugated to biotin under optimal conditions. The biotinylated antibody is expected to exhibit the same species cross-reactivity as the unconjugated HER3/ErbB3 (D22C5) XP® Rabbit mAb #12708.
