Presentation transcript:

The effects of different adhesive tapes and of Hemastix test strips on DNA recovery using magnetic silica beads  Stefan Kutranov, Holly Cullis  Forensic Science International: Genetics Supplement Series  Volume 3, Issue 1, Pages e212-e213 (December 2011) DOI: 10.1016/j.fsigss.2011.08.106 Copyright © 2011 Elsevier Ireland Ltd Terms and Conditions

Fig. 1 DNA yield from single-sided tape samples, which showed bead clumping, is reduced as compared to double-sided tape samples, which did not show bead clumping, and to tape-free samples. Left: Quantification Data, Right: numbers of peaks seen in SGM plus profiles.

Fig. 2 DNA yield from swabs contaminated with Hemastix reagents. Yield is greater from samples that have not come into direct contact with Hemastix Reagent Strips than with samples that have. Left: strong samples (1 in 2 dilution), Right: weak samples (1 in 40 dilution).
