POLR2E Fragment MS Protein Standard


Product Description

NamePOLR2E Fragment MS Protein Standard
SynonymsDNA-directed RNA polymerase II 23 kDa polypeptide, DNA-directed RNA polymerase II subunit E, RPB5 homolog, XAP4
Uniprot IDP19388
Protein NameDNA-directed RNA polymerases I, II, and III subunit RPABC1
DescriptionPOLR2E Fragment MS Protein Standard, is a protein fragment containing a 50-150 amino acid sequence identical to part of a human POLR2E protein target. The fragment MS Protein Standard represents a new category of using heavy isotope labeled (15N, 13C) Lysine and Arginine residues resulting in more than 99% isotope incorporation, as internal MS standards offering distinct advantages to existing products for relative and absolute quantification.
