LC–MS analysis of Mb in PAM-MSCs, MAT-MSCs and DP-MSCs. A SDS-PAGE referring gel showing the excised bands subjected to trypsinization. B Sequence of human Mb with the putative sites of trypsinization indicated in bold (K, R). C LC–MS extract ion chromatograms identified in each of the bands indicated in (A) human Mb tryptic fragments; the peptide sequences and their M.W. are shown at the top of each panel lane
