This is a tryptic peptide fragment obtained from C-reactive protein in which the phenylalanine residue is heavy isotope labeled (13C9, 15N1). This peptide has been used in isotope dilution mass spectrometry studies involving the quantification of C-reactive protein in biological samples. C-reactive protein is an important prognostic and diagnostic marker in cardiovascular disease and cancer.
