Data for the optimization of conditions for meat species identification using ultra-fast multiplex direct-convection PCR.

ABSTRACT: This article contains data related to the research article entitled "Ultra-fast DNA-based multiplex convection PCR method for meat species identification with possible on-site applications" (Song et al., 2017 [1]). Direct PCR that does not require prior DNA extraction is critical for ultra-fast molecular detection of meat species. We successfully acquired DNA by swab sampling in Taq DNA polymerase buffer. To reduce DNA sample preparation time, proteinase K incubation (0.2 ?g/mL) and heat inactivation times were decreased to 10 min and 1 min, respectively. The analysis of swabbed DNA samples from mixed meat could differentiate meat species within the mixed sample. The swabbed DNA samples could be diluted 100 times without losing detection sensitivity.

Project description:Due to its proficiency to provide the most discriminating results for forensic applications, medical research and anthropological studies, multiplex PCR based STR analysis has been established as the most efficient technique in the forensic DNA analysis. Several multiplex amplification kits based on 4, 5 and 6 dyes chemistry are commercially available and used in forensic DNA typing across the globe. These multiplex PCR systems are routinely used for amplification of multiple STR loci (Autosomal, Y and/or X STR's) in the DNA extracted from various biological samples. In the routine forensic DNA testing, DNA profile obtained is compared with the DNA profile of the reference sample, which takes a certain turnaround time and employs costly lab resources. Successive development in forensic DNA typing have resulted in advent of improved multiplex kits which have reduced the effective analysis time, cost and minimized the number of steps required in comparison to conventional forensic DNA typing. Specialized direct amplification compatible multiplex kits are also available nowadays. These kits are relatively costlier but still require few pre-processing steps, which does not make them worth the hefty cost. Herein, this study, we have used non-direct multiplex STR kits to assess their efficacy for direct amplification. In the present study, 103 saliva samples were directly amplified without any pre-treatment of the samples using thirteen non-direct multiplex kits (4 dyes, 5 dyes and 6 dyes chemistry based) for forensic DNA typing. Here, we report a validated direct PCR amplification protocol from the reference saliva samples by omitting DNA extraction and quantification steps, which resulted in 80% reduction of the turnaround time. The developed protocol is cost effective, time efficient and it does not compromise with the quality of DNA profiles. To the best of our knowledge, this is the first report for direct amplification of DNA with the most commonly used non-direct multiplex STR kits without any pre-treatment of the sample. Complete DNA profiles matching all the essential quality parameters were obtained successfully from all the tested samples.
