Little to no allelic drop out was observed when 500 pg of DNA was

Little to no allelic drop out was observed when 500 pg of DNA was amplified, and several samples Stem Cells inhibitor with less than 200 pg yielded full profiles. When partial

profiles were generated, significant genotype information was generally collected. Although clear amplification inhibition was observed in a reaction with 76 pg of DNA extracted from leather, information from 14 loci was retrieved (Supplemental Fig. 5). Amplification was seen with all touch samples, and as expected, several contributors were detected. Samples known to have multiple contributors produced allele calls consistent with the contributor profiles. Although no single contributor profile was complete, three of four mixed samples produced significant profile information with at least one allele at all autosomal loci using ≤210 pg total template DNA (Supplemental

Fig. 6). In these partial profile case-type samples, allelic drop out occurred with the largest loci, TPOX, D22S1045, DYS391, and Penta E, which see more are either less informative or not required by databases. Full or significant partial profile information was successfully collected with typical case-type samples using a range of template amounts.

the ratios: 1:0, 19:1, 9:1, 5:1, 2:1, 1:1, 1:2, 1:5, 1:9, 1:19, 0:1. Five sites amplified a total quantity of 500 pg of DNA for 30 cycles. Alleles unique to the minor contributor were counted and presented as a percentage of the total number of unique alleles expected (percent unique alleles called). Multiple contributors were detected with all mixture ratios at all five test sites. An average of 88% of unique minor contributor alleles were detected in 1:9 mixture ratios and an average of 55% were detected in 1:19 mixture ratios (Supplemental Fig. 7). The minor donor contribution in these samples was 50 pg and 25 pg, respectively. Similar Protein kinase N1 results were gathered with Applied Biosystems® 3130 and 3500 Series Genetic Analyzers. As the mixture ratio increased, the average number of alleles detected decreased. These results are comparable to what has been reported with smaller, 16- and 17-locus multiplexes [10] and [11], indicating that the addition of loci has not compromised performance for mixture analysis.
