Abstract:
To evaluate the forensic validation of D20S161 and D8S384 loci.Two typing kits for D20S161 and D8S384 had been home made.The samples had been analyzed by using both kits,which including human blood,human semen,human saliva,animal blood,mixture of human blood and animal blood;human bloodstain,human semen stain,human saliva stain,animal bloodstain, mixture stain of human blood and animal blood; old bloodstains.The sequences of primers for both loci had been compared with 606364 sequences in data base in GeneBank,USA.There are positive results for human blood,human semen,human saliva,mixture of human blood and animal blood by using both kits for D20S161 and D8S384 loci.But animal bloods have not any PCR-productyet.Genotyping of human bloodstain,human semen stain,human saliva stain,mixture stain of human blood and animal blood by using both kits for D20S161 and D8S384 loci were correct.But animal bloodstains had not any PCR productyet.Also, all of fifty old bloodstains had positive results of typing for D20S161 and D8S384.No product was obtained by PCR technigue when primers for both D20S161 and D8S384 loci were tested against 606364 known sequences in the data base in GeneBank.The results demonstrated that both loci have species specificity.Both D20S161 and D8S384 loci are useful marker for forensic casework and paternity analysis.
