Minisatellite variant repeat (MVR) mapping using the polymerase chain reaction (PCR) at D1S8 (MS32) was applied to samples from various human tissues. All DNA samples obtained from an individual's organs at autopsy consistently gave the same digital diploid codes. Even 1 ng of genomic DNA was sufficient to obtain authentic diploid MVR coding ladders. MVR-PCR could be reliably applied to DNA isolated from bloodstains, saliva stains, seminal stains and plucked hair roots, and should become a powerful tool for individual identification in forensic investigations.
