[Application of the PCR-APLP method to determine ABO genotypes in forensic samples]

We carried out ABO genotyping of forensic samples by the amplified product length polymorphism (APLP) technique. We present two novel systems. One is termed as eight primers system, in which eight allele-specific primers are added into a single PCR reaction. Another is termed as six primers system. In both APLP systems, all alleles were clearly detected using DNA purified from forensic samples. In PCR amplification with direct addition of specimen, ABO genotyping was also possible to blood stain, seminal stain, blood, saliva and urine. Furthermore, ABO genotyping worked only to chimpanzee. This PCR-APLP method should be convepffnt and valuable for forensic practice.
