Description
Rpb1 NTD (D8L4Y) Rabbit mAb recognizes endogenous levels of total Rpb1 protein at the amino terminal domain (NTD). Phospho-Rpb1 CTD (Ser2) (E1Z3G) Rabbit mAb recognizes endogenous levels of Rpb1 only when the carboxy-terminal domain (CTD) heptapeptide repeat [Tyr1, Ser2, Pro3, Thr4, Ser5, Pro6, Ser7] is phosphorylated at Ser2. This antibody does not cross-react with Rpb1 CTD phosphorylated at Ser5 or Ser7. Phospho-Rpb1 CTD (Ser5) (D9N5I) Rabbit mAb 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 Ser2 or Ser7. Phospho-Rpb1 CTD (Ser2/Ser5) (D1G3K) Rabbit mAb recognizes endogenous levels of Rpb1 only when the carboxy-terminal domain (CTD) heptapeptide repeat [Tyr1, Ser2, Pro3, Thr4, Ser5, Pro6, Ser7] is dually phosphorylated at Ser2 and Ser5. This antibody does not cross-react with Rpb1 CTD that is singly phosphorylated at Ser2, Ser5, or Ser7. Phospho-Rpb1 CTD (Ser7) (E2B6W) Rabbit mAb recognizes endogenous levels of Rpb1 protein only when the carboxy-terminal domain (CTD) heptapeptide repeat [Tyr1, Ser2, Pro3, Thr4, Ser5, Pro6, Ser7] is phosphorylated at Ser7. This antibody does not cross-react with Rpb1 CTD phosphorylated at Ser2 or Ser5
