Evaluation of Library Preparation Workflows and Applications to Different Sample Types Using the PowerSeq 46GY System with Massively Parallel Sequencing.

This project evaluated the prototype PowerSeq 46GY System using donor DNA and casework-type samples. The goal of this study was to determine whether modifications to the manufacturer's protocol could increase read coverage and improve sample results. Buccal and casework-type libraries were prepared using the TruSeq DNA PCR-Free HT kit or the KAPA HyperPrep kit.

Assessment of detection limits for dyed and mounted textile fibers using Raman spectroscopy.

Trace evidence in the form of textile fibers can be used to link objects and places during an investigation. Raman spectroscopy is a well-established technique that has been used for the examination of various pigments, paints, inks, and dyes. The objective of this study was to determine the capability of Raman spectroscopy to detect several different dye classes and colors on a variety of textile fibers.

Combining multiplex PCR and high-resolution melting for the detection and discrimination of arthropod transmitted viruses of cereals.

The Great Plains of the United States is a region comprised of approximately 45 million hectares of grasslands where several economically important cereal crops are grown. Arthropod-transmitted, cereal-infecting viruses vary in incidence from year-to-year and are often difficult to detect in large acreages. To facilitate the detection of economically important viruses of cereals that often exist in co-infections, a multiplex reverse transcriptase PCR (RT-PCR) platform assay was developed.
