Theses and Dissertations

“Touch” DNA is evidence that consists of epidermal cells deposited by handling objects and it is becoming more common in evidence samples processed in crime labs. Because “touch” DNA evidence samples may be low-template DNA and are often mixtures, there is a need to both nondestructively estimate the amount of DNA present prior to DNA purification and to identify and characterize mixtures prior to DNA typing. The purpose of this study was to test the use of FITC-labeled anti-testosterone antibodies as a potential tool to estimate the number of contributors in two-, three-, and four-person mixtures of epidermal skin cells, …
