Table 2

Theoretical peaks of two peptides MYLGYEYVTAIR and LGEYGFQNALLVR. Both peptides are found to be significant by RAId_DbS for a given query spectrum and were found to be partial sequences of proteins originally put in for the experiment. The right column lists the b y peaks of both peptides in ascending m/z order. The two sets of theoretical peaks only have two pairs that are within three daltons of each other. They are (175.12, 175.12) and (1019.45, 1017.58). This negligible overlap between theoretical peaks reinforces the possibility of co-elution of the two peptides during the experiment
