NFSTC at AAFS 2011 – Register to win an iPad!

NFSTC is providing a variety of forensic science presentations this week at the AAFS Annual Meeting in Chicago. Exhibits include poster presentations on DNA Quantitation, Field-Purposing Technologies and a comparison of four portable Raman Spectrometers. In addition, our instructional design group is providing a presentation on Blended Learning for Forensic Science Disciplines and the NamUs team is demonstrating their online system (booth #629).

To demonstrate NFSTC’s hands-on training, we’ve enhanced our booth this year by constructing a mock crime scene. If you’re attending the AAFS symposium, stop by booth #1008 to work the scene, learn about new forensic technologies and register to win an iPad!

NFSTC lab evaluates DeltaNu® ReporteR™ portable Raman spectrometer

NFSTC conducted an evaluation of the performance of the DeltaNu® ReporteR™ Portable Raman Spectrometer in order to provide laboratories with information to assess the strengths and limitations of this Raman technology for evidence identification.

NFSTC releases evaluation of the Applied Biosystems AmpFℓSTR® Identifiler® Plus STR amplification kit

To assist forensic laboratories in understanding the general performance of commercially available STR amplification kits, NFSTC has evaluated the Applied Biosystems AmpFℓSTR® Identifiler® Plus amplification kit as an addition to a previous study of eight kits manufactured by Applied BiosystemsTM and Promega Corporation. The kits were assessed for: sensitivity, peak height ratios at heterozygous loci, baseline noise, stutter ratio and amplification artifacts. These criteria were evaluated by analysis of single-source human DNA samples and a mixture series.

The current study was performed using the same sample set and performance standards as the previous amplification kit study.
