Polymerase chain reaction (PCR) amplification using formalin-fixed material is very limited. In the present study the use of 6 week formalin-fixed placenta for individual identification was examined based on DNA analyses. The objective of the examination was to prove whether the placenta was from a woman who had just given birth. DNA extraction was carried out from the maternal blood sample and from the formalin-fixed placental samples composed of three parts: maternal side, infant side and umbilical cord. One minisatellite (D1S80), 12 short tandem repeat (STR) polymorphisms and amelogenin X, Y were investigated. All the polymorphic systems were detected in the maternal blood sample. The majority of the DNA isolated from the placental tissues had molecular weights of approximately 500 bp, and only two to four STR loci were amplified using the DNA. In order to amplify more DNA polymorphic markers from the formalin-fixed tissues, whole genome amplification was performed. After amplification by degenerate oligonucleotide-primed PCR (DOP-PCR), the products contained DNA with increased molecular weight up to >10 kbp. More DNA loci were typed using the DOP-PCR products. Furthermore, large molecular size fragments were purified from the DOP-PCR products by agarose electrophoresis, and then the D1S80 locus and 12 STR loci were successfully amplified using these fragments.
