Fingerprints and DNA: STR typing of DNA extracted from adhesive tape afterprocessing for fingerprints

An exhibit that is often received for examination in cases of robbery or te rrorist activity is adhesive tape. This type of exhibit can often, but not always, be successfully processed for fingerprints. The question arises whe ther or not it is possible to extract and type DNA after the tape has been sequentially processed for fingerprints. In this work, various donors left fingerprints on the adhesive side of rapes. The tapes were then sequentiall y processed for fingerprints using an alternate light source, cyanoacrylate fuming, and staining with BY-40 and then crystal violet. DNA was subsequen tly successfully extracted, amplified and typed for six STR loci.
