Profiles generated from DNA recovered from touched items*
| Sample group | No (%) of samples amplified | No (%) of database eligible samples in each group | No (%) of database eligible samples of total amplified (n = 39) |
|---|---|---|---|
| 10 pg – 19 pg – single source | 9 (23.1) | 2 (22.2) | 2 (5.1) |
| 10 pg – 19 pg – non-deducible mixtures | 1 (2.6) | N/A | N/A |
| 20 pg – 100 pg – single source | 18 (46.1) | 17 (94.4) | 17 (43.6) |
| 20 pg – 100 pg – deducible mixtures | 7 (17.9) | 5 (71.4) | 5 (12.8) |
| 20 pg – 100 pg – non-deducible mixtures | 4 (10.3) | N/A | N/A |
| Total | 39 (100.0) | N/A | 24 (61.5) |
*DNA in the low template DNA range was recovered from 39 samples from touched or handled items or single fingerprints. Sample groups were defined according to the amount of DNA amplified in each of 3 replicates and whether the resulting profiles were from 1 source or were mixtures wherein the major component could or could not be resolved. Data are expressed as the number or percentage of either samples amplified or database eligible profiles which contain at least 6 complete loci and 10 loci overall.
