Description
POLR1C Fragment MS Protein Standard, is a protein fragment containing a 50-150 amino acid sequence identical to part of a human POLR1C 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.
Synonyms
AC40, DNA-directed RNA polymerases I and III 40 kDa polypeptide, RPA39, RPC40
