Recent Developments in Y STR and Y SNP Analysis

October 16, 2008
Author(s)
John Butler
This article reviews new genetic markers on the Y chromosome and methods for analyzing these short tandem repeat (STR) and single nucleotide polymorphism (SNP) loci. Relative chromosomal locations for over 50 Y STRs are described along with their repeat

Characterization of 26 miniSTR loci for improved analysis of degraded DNA samples

January 25, 2008
Author(s)
Carolyn R. Steffen, Margaret C. Kline, Michael Coble, John M. Butler
An additional 20 novel mini-short tandem repeat (miniSTR) loci have been developed and characterized to aid in the analysis of degraded DNA samples. These new markers produce short PCR products in the target range of 50 150 base pairs (bp) by moving the

Concordance Study Between the AmpFlSTR((R)) MiniFiler(TM) PCR Amplification Kit and Conventional STR Typing Kits

July 25, 2007
Author(s)
Carolyn R. Steffen, Margaret C. Kline, Julio J. Mulero, Robert E. Lagace, Chien-Wei Chang, Lori K. Hennessy, John M. Butler
The AmpFlSTR MiniFiler PCR Amplification kit developed by Applied Biosystems enables size reduction on eight of the larger short tandem repeat (STR) loci amplified in the Identifiler kit, which will aid recovery of information from highly degraded DNA

Analysis of artificially degraded DNA using STRs and SNPs results of a collaborative European (EDNAP) exercise

December 1, 2006
Author(s)
L. A. Dixon, A. E. Dobbins, H. Pulker, John M. Butler, Peter M. Vallone, Michael D. Coble, W. Parson, B. Berger, P. Grubwieser, H. S. Mogensen, N. Morling, K. Nielsen, J. J. Sanchez, E. Petkovski, A. Carracedo, P. Sanchez-Diz, E. Ramos-Luis, M. Brion, J. A. Irwin, R. S. Just, O. Loreille, T. J. Parsons, D. Syndercombe-Court, H. Schmitter, B. Stradmann-Bellinghausen, K. Bender, P. Gill

Setting standards and developing technology to aid the human identity testing community

April 1, 2006
Author(s)
John M. Butler, Michael D. Coble, Amy E. Decker, David L. Duewer, Carolyn R. Steffen, Margaret C. Kline, Janette W. Redman, Peter Vallone
Our project team at the U.S. National Institute of Standards and Technology (NIST) is funded by the National Institute of Justice (NIJ) to conduct research that benefits the human identity testing community and to create tools that enable forensic DNA

The evaluation of an autosomal SNP 12-plex assay

April 1, 2006
Author(s)
Peter M. Vallone, Amy E. Decker, Michael D. Coble, John M. Butler
SNPs have the potential to play a useful role in human identification testing. Small PCR amplicon sizes associated with SNP typing technologies make SNPs attractive for typing degraded DNA or other low copy number situations. SNP markers can be useful in

Analysis of DNA Single Nucleotide Polymorphisms by Mass Spectrometry

March 17, 2006
Author(s)
Peter Vallone, John Butler
Single nucleotide polymorphisms(SNP) are the most frequent form of DNA sequence variation in the human genome and are becoming increasingly useful as genetic markers for genome mapping studies, medical diagnostics, and human identity testing. The primer

DNA Identifications After the 9/11 World Trade Center Attack

November 18, 2005
