Protein Found At The Scene Of The Crime: The Potential For Using Proteomics For Identification, Gavin R. Tisdale

Dissertations and Honors Papers

Hair has long been collected from crime scenes as part of trace evidence. Originally, hair was used for some exclusionary purposes—only general qualities about an unknown source could be determined. Eventually, DNA was used to help identify the source but only if the root was still attached. Within the last two years, however, two major studies have used proteomics—the study of human protein sequences—to extract and identify protein sequences in an unknown source in order to match it to a known source. These two studies support the same hypothesis: proteomics is currently a viable method for narrowing down the source …
