Author(s)
John M. Butler, R Schoske
Population studies are important in forensic science and human identity testing to help demonstrate that STR markers are polymorphic and will help distinguish the various individuals from one another. A total of 679 male DNA samples from 3 U.S. populations

Results From the NIST 2004 DNA Quantitation Study

Author(s)
Margaret C. Kline, David L. Duewer, Janette W. Redman, John M. Butler
For optimal DNA Short Tandem Repeat (STR) typing results, the DNA concentration ([DNA]) of the sample must be accurately determined prior to the polymerase chain reaction (PCR) amplification step in the typing process. In early 2004, the National Institute

Mitochondrial DNA Typing Screens With Control Region and Coding Region SNPs

March 1, 2005
Author(s)
Margaret C. Kline, Peter M. Vallone, Janette W. Redman, David L. Duewer, C D. Calloway, John M. Butler
Mitochondrial DNA (mtDNA) analysis has found an important niche in forensic DNA typing. It is used with highly degraded samples or low-copy number materials such as might be found from shed hair or bones exposed to severe environmental conditions. The
