Description
Phospho-Rpb1 CTD (Ser5) (D9N5I) Rabbit mAb (Biotinylated) recognizes endogenous levels of Rpb1 only when the carboxy-terminal domain (CTD) heptapeptide repeat [Tyr1, Ser2, Pro3, Thr4, Ser5, Pro6, Ser7] is phosphorylated at Ser5. This antibody does not cross-react with Rpb1 CTD phosphorylated at Ser5 or Ser7
