Fig. 5. Extracted ion chromatograms (A–C) and MRM spectra (D–F) of transitions monitored for SS-DLVALSGGHTFGK derived from HRP in nonfractionated, depleted plasma.

Fig. 5

Overlay of XICs and the corresponding MRM spectra for the three transitions monitored for SSDLVALSGGHTFGK peptide of HRP in 0.1% formic acid (A and D) and the same peptide produced by digestion of HRP protein that had been spiked at 25 (B and E) or 100 ng/ml (C and F) into IgY-12 depleted plasma. XICs and ions in the MRM/MS spectra are color-coordinated. cps, counts/s.
