| Research Abstract |
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
