Thermo Fisher, 4441351, PrepFiler <i>Express</i> BTA™ Forensic DNA Extraction Kit

PrepFiler Express BTA™ Forensic DNA Extraction Kit is designed for extraction and purification of forensic DNA from challenging sample types using the AutoMate Express Forensic DNA Extraction System. The PrepFiler Express BTA workflow supports difficult specimens including bone, teeth and adhesive substrates such as cigarette butts, chewing gum and tape lifts. Manual preparation of the sample lysate is followed by automated DNA purification using magnetic-bead chemistry and prefilled instrument cartridges. The kit includes BTA lysis buffer, Proteinase K, LySep columns, bone-and-tooth lysate tubes and caps, instrument tips and holders, cartridges, sample tubes and elution tubes. The LySep column retains solid substrate during lysate separation, reducing the need to transfer particulate material manually into the automation system. Its closed purification workflow helps limit sample cross-contamination and handling errors. The kit contains reagents and consumables for 52 preparations and supports batches of 1–13 samples per AutoMate Express run. The resulting purified DNA can be used for forensic qPCR quantification and short tandem repeat analysis. Store at 18–25 °C. This BTA version includes components tailored for hard tissue and adhesive evidence rather than the standard-sample workflow alone.
