Fractionation of DNA and Protein from Individual Latent Fingerprints for Forensic Analysis

Abstract: Human touch samples represent a significant portion of forensic DNA casework. Yet, the generally low abundance of genetic material combined with the predominantly extracellular nature of DNA in these samples makes DNA-based forensic analysis exceptionally challenging. Human proteins present in these same touch samples offer an abundant and environmentally-robust alternative.... MORE

DNA-Touch™ – Synthetic Fingermarks for Genomics Research

Variability in the amount of DNA deposited by individuals when touching a surface poses a significant hurdle to the evaluation of forensic analysis methods for touch samples. No two human latent fingerprint samples are the same due to the “shedder” status of different individuals as well as other factors including... MORE

Probabilistic Genotyping Brings Benefits to DNA Casework

The interpretation of DNA mixtures continues to be a pervasive topic in the field of forensic DNA analysis. With the long awaited publication of the NIST MIX05 MIX13 study, and an increasing number of DNA laboratories turning to probabilistic genotyping, it’s worth stopping for a moment to consider just how the...
