Imaging of mixed body fluid stain by MALDI-TOF-MS

在10名健康青年志愿者精液和精液染色液中，以高强度m/z 2890为特征大分子。此外，将精液、血液、尿液和唾液的每个污点都贴上一块棉布，然后将其转移到一张导电的双面碳胶带上，然后用maldi成像检测精液污点的位置，并在复制品上使用m/z 2890（作为分子标记）。maldi成像可能是一种有用的工具，用于在使用和目前信任的测试之前筛选精液污渍的位置

It was detected as characteristic macromolecule at high intensity on m/z 2890 in semen and seminal stain extract from ten healthy young volunteers. In addition, a sheet of cotton cloth attaching each stain of semen, blood, urine, and saliva was transferred to a sheet of conductive double sided carbon adhesive tape, following that the locations of seminal stains were detected by MALDI-imaging with m/z 2890 (as a molecular marker) on the replica. MALDI-imaging might be a useful tool for screening of the locations of seminal stains before tests that have been used and are currently trusted
