Table 3.

Peptide ratios suggested for estimation of three different postmortem periods (< 200 accumulated degree days (ADD), < 655 ADD and < 1535 ADD; listed are the mass-to-charge ratios (m/z) and retention times (RT) of each peptide along with the amino acid sequence, protein origin (with alternative possible origin listed in brackets) and the results of the linear regression (coefficient of determination (r2) and slope); [Carba]: carbamidomethyl modification; [OX]: oxidation modification

Feature ratio [m/z_RT] Peptide ratio Protein origin r2 Slope
