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.

NFSTC tests mini-vacuum for collection of DNA

The most common method of collecting DNA is swabbing. It’s effective, affordable and has been used for decades. But is there a better method than the tried-and-true swab technique to collect biological evidence? To determine if the BioTx Innovac® II, a small, lightweight vacuum device, was more efficient at collecting DNA from a variety of surfaces, NFSTC conducted a thorough evaluation.
