Dear ABRF,

Recently I tried in-gel digestion of several 2D gel protein spots with trypsin.
Several peaks with masses of 1941.46, 2239.38, 2461.19 and 2807.45 from Maldi-Ms
data appear to be contaminations. However I don't know where they come from.
Has anyone had these results before? And their sources?

Thanks.
