| Abstract: | PCR followed by SDS-PAGE in miniaturized non-denaturing gels permits in some cases the identification of single base pair substitutions in small DNA fragments and therefore, the study of human DNA polymorphisms. The usefulness of the system in forensic science is investigated by typing the HLA-DQA1 locus and the VNTR recognized with the probe pMCT118 (locus D1S80) and it shows to be advantageous over previously published methods for typing the MCT118 system, whereas in HLA-DQA1 typing for forensic casework, both dot-blot with ASO probes and this method could be complementary. |
