Differentiation of Asian population samples using the Illumina ForenSeq kit.

The Kidd set of ancestry informative SNPs are included in Illumina's ForenSeq DNA Signature Kit. We had previously reported on the capability of these SNPs together with some phenotypic SNPs with ancestry informative properties in differentiating individuals from the Chinese, Malay and Indian populations in Singapore. The Singapore population is primarily made up of Chinese, Malays and Indians, with individuals from other Asian countries making up the rest.

A practical study on direct PCR amplification using the GlobalFiler™ PCR Amplification Kit on human bloodstains collected with microFLOQ™ Direct swabs.

Rapid DNA profiling of casework samples is a powerful tool that can support law enforcement agencies in the quick apprehension of perpetrators before they re-offend or escape the jurisdiction. This present study evaluated the feasibility of direct PCR amplification, using the microFLOQ™ Direct swab, for generating DNA profiles (from bloodstains) within 3 h. The swab tip is coated with nylon fibers pre-treated with cell lysing agent, which allows for the direct PCR amplification of collected samples without DNA extraction and quantification, thereby shortening the time required to obtain a DNA profile.

Ancestry prediction in Singapore population samples using the Illumina ForenSeq kit.

The ability to predict bio-geographic ancestry can be valuable to generate investigative leads towards solving crimes. Ancestry informative marker (AIM) sets include large numbers of SNPs to predict an ancestral population. Massively parallel sequencing has enabled forensic laboratories to genotype a large number of such markers in a single assay.
