Figure 4

Detection of Y chromosomal element by semi-nested PCR of PSTT DNA. A strong positive product of 307 bp is present in both positive control specimens, but absent in all PSTT. Lane 1: 100 bp DNA marker. Lanes 2 to 6: PSTT case #1 to 5. Lanes 7 and 8: positive controls using DNA template from two male tissues. Several faint smaller bands in lane 6 are non-specific products.
