In order to have access and use the Combined DNA Index System (CODIS), it is required by the Federal Bureau of Investigation's Quality Assurance Standards (FBI-QAS) for Forensic DNA Units to complete comprehensive validation studies on all equipment, materials, and methods used in the process of DNA analysis. This study continues validation previous done within the Ohio Bureau of Criminal Investigation (BCI). YFiler Plus is a DNA amplification kit that is used in cases where it is most useful to examine only male DNA profile(s) within a sample by amplifying loci only on the Y-Chromosome. Components of this study include …

The Escherichia coli ferric hydroxamate uptake receptor FhuA serves as the receptor for ferrichrome-Fe(III) complexes, with TonB protein energizing the active transport of the complex. The FhuA receptor is exploited by a variety of bacteriophages as a conduit into the cell. Interestingly, certain of these phages carry a gene called “Cor”, the product of which, when cloned and expressed from a plasmid, blocks transport by FhuA. In the present study, components of the cor gene from the bacteriophage ϕ80 were used to construct an IPTG-inducible MalE-Cor-His6 fusion protein, which allowed for affinity purification of the Cor protein. At 61 residues …

The oomycete Phytophthora parasitica has a worldwide distribution and is an economically important pathogen of more than 100 species4. RNA-seq analysis showed that one gene, PPTG_16698 has the 5th highest level of expression of all transport proteins in the zoospore stage, and is highly conserved throughout Phytophthora species. This project attempts to characterize the important biological role that PPTG_16698 plays in P. parasitica and other oomycetes. Three strategies have been implemented to accomplish this goal: growth analysis by heterologous expression in yeast, metabolite analysis in yeast, and construction of a GFP fusion protein to enable localization of …
