Description: Supplied by Covance, cat# MMS-129R The antibody H5 was developed against a purified phosphorylated form of RNA polymerase II extracted from a transformed cell line. Pol II has two physiologically important phosphorylation sites; ser-2 and ser-5. Both sites are found in the heptapeptide repeat YSPTSPS at the C-terminal domain. This antibody recognizes the phosphoserine 2 version of pol II.
