- Title
A Protocol for the Recovery of STR DNA from Fingerprints Developed on the Adhesive Side of Duct Tape.

- Abstract
When adhesive tape becomes an item of physical evidence, the adhesive side can be examined for fingerprint impressions, hairs, fibers, paint, soil, and DNA. The use of a powder suspension method is effective in visualizing and documenting fingerprint impressions on the adhesive side of duct tape. Visible fingerprints, identifiable or not, can then be swabbed for recovering DNA evidence for identification purposes. This project demonstrates that fingerprints deposited on the adhesive side of duct tape can be recovered using nucleic acid-compatible solvents such as chloroform or heptane. COPAN 4N6 FLOQSwabs facilitated the solubilization of the adhesive and the absorption of the organic solvent containing the DNA sample. This protocol was effective in recovering the donor's full STR DNA profile from fingerprints collected on duct tape over a period of 18 months.
