WebDetermination of genotypes at this VNTR locus can now be routinely achieved within 24 h, without the need for Southern blots or radioactive materials. Furthermore, the small size … WebIn one study of 197 Danes, 53 different alleles in D12S391 were detected by NGS, whereas only 15 different alleles were detected by PCR-CE. Many alleles in D12S391 have the same length but different sequence compositions in the repeat region. So far, the top score is eight different alleles with a length equivalent to 21 repeats (Table 22.1) [66]. food on table images
