? Indicates peak is present but at low intensity, or below signal to noise threshold. The presence/absence of a particular peptide marker is denoted by letters P1, P2, A-G; A = α2(I) 988–1000; B = α2(I) 494–508; C = α2(I) 512–529; D = α2(I) 803–826; F = α1(I) 602–634; G = α2(I) 767–799. “—” Indicates no peak was present. Where two m/z values are given, the presence of both is required. Bold italicised text indicates species specific markers. With the exception of the white-tailed deer and the three DR samples, the cervid m/z markers are from published sources19,49,50. The white-tailed deer m/z markers were determined from spectra obtained from a known reference specimen.
