A developmental validation of the Quick TargSeq 1.0 integrated system for automated DNA genotyping in forensic science for reference samples. Electrophoresis 2024; 45:814-828. [PMID: 38459798 DOI: 10.1002/elps.202300187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 02/07/2024] [Accepted: 02/21/2024] [Indexed: 03/10/2024]
Abstract
Analysis of short tandem repeats (STRs) is a global standard method for human identification. Insertion/Deletion polymorphisms (DIPs) can be used for biogeographical ancestry inference. Current DNA typing involves a trained forensic worker operating several specialized instruments in a controlled laboratory environment, which takes 6-8 h. We developed the Quick TargSeq 1.0 integrated system (hereinafter abbreviated to Quick TargSeq) for automated generation of STR and DIP profiles from buccal swab samples and blood stains. The system fully integrates the processes of DNA extraction, polymerase chain reaction (PCR) amplification, and electrophoresis separation using microfluidic biochip technology. Internal validation studies were performed using RTyper 21 or DIP 38 chip cartridges with single-source reference samples according to the Scientific Working Group for DNA Analysis Methods guidelines. These results indicated that the Quick TargSeq system can process reference samples and generate STR or DIP profiles in approximately 2 h, and the profiles were concordant with those determined using traditional STR or DIP analysis methods. Thus, reproducible and concordant DNA profiles were obtained from reference samples. Throughout the study, no lane-to-lane or run-to-run contamination was observed. The Quick TargSeq system produced full profiles from buccal swabs with at least eight swipes, dried blood spot cards with two 2-mm disks, or 10 ng of purified DNA. Potential PCR inhibitors (i.e., coffee, smoking tobacco, and chewing tobacco) did not appear to affect the amplification reactions of the instrument. The overall success rate and concordance rate of 153 samples were 94.12% and 93.44%, respectively, which is comparable to other commercially available rapid DNA instruments. A blind test initiated by a DNA expert group showed that the system can correctly produce DNA profiles with 97.29% genotype concordance with standard bench-processing methods, and the profiles can be uploaded into the national DNA database. These results demonstrated that the Quick TargSeq system can rapidly generate reliable DNA profiles in an automated manner and has the potential for use in the field and forensic laboratories.

Laurin N, Boulianne H, Frégeau C. Comparative analysis of two Rapid DNA technologies for the processing of blood and saliva-based samples. Forensic Sci Int Genet 2023; 67:102928. [PMID: 37573630 DOI: 10.1016/j.fsigen.2023.102928] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 07/30/2023] [Accepted: 08/07/2023] [Indexed: 08/15/2023]
Abstract
Rapid DNA technologies recently gained significant momentum as a means to generate DNA profiles faster than with standard laboratory workflows. Initially developed for the analysis of buccal reference samples, applications are being considered for other types of forensic samples. In this study, an identical set of 150 blood and saliva-based samples was processed using two different Rapid DNA technologies, the Applied BioSystems™ RapidHIT™ ID System using the RapidINTEL™ sample cartridge and the ANDE™ 6C Rapid DNA Analysis™ System using the I-Chip. A subset of samples were subjected to alternative collection methods or sample pre-treatments to determine the optimal strategy for each instrument. An equivalent sample set was also processed using a conventional DNA analysis workflow. The sensitivity range of the two Rapid DNA technologies was comparable based on blood and saliva dilution series, with both technologies able to generate full profiles from samples typically yielding 5-10 ng of DNA when processed using conventional DNA analysis. The brand of cotton swabs used for Rapid DNA analysis had an impact on the results for both systems. Differences were observed in success rate between the two systems when processing blood (on fabrics, FTA paper or hard surfaces) and saliva-based samples (drink containers, FTA paper, chewing gum, cigarette butt filter paper) and depended on the sample type. Importantly, deviating from the manufacturer's instructions for sample collection and pre-treatment was more detrimental to the ANDE 6C results. The quality of DNA profiles, as assessed using heterozygote peak height ratios, interloci balance and artifact presence, confirmed the results to be reliable and acceptable for single source samples. Profiling results were obtained when samples were reprocessed using the same Rapid DNA technology or conventional DNA analysis. Secondary analysis using a substitute software (GeneMapper ID-X v1.5) to recover additional genetic information was shown to be feasible. Finally, a comparison between the Applied Biosystems™ RapidHIT™ ID System Software v1.3.1 and v1.3.2 was also performed. Findings of this study could assist those interested in using Rapid DNA technology for blood or saliva-based samples, in various settings and for different applications.

Bruijns B, Knotter J, Tiggelaar R. A Systematic Review on Commercially Available Integrated Systems for Forensic DNA Analysis. SENSORS (BASEL, SWITZERLAND) 2023; 23:1075. [PMID: 36772114 PMCID: PMC9919030 DOI: 10.3390/s23031075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 01/11/2023] [Accepted: 01/12/2023] [Indexed: 06/18/2023]
Abstract
This systematic review describes and discusses three commercially available integrated systems for forensic DNA analysis, i.e., ParaDNA, RapidHIT, and ANDE. A variety of aspects, such as performance, time-to-result, ease-of-use, portability, and costs (per analysis run) of these three (modified) rapid DNA analysis systems, are considered. Despite their advantages and developmental progress, major steps still have to be made before rapid systems can be broadly applied at crime scenes for full DNA profiling. Aspects in particular that need (further) improvement are portability, performance, the possibility to analyze a (wider) variety of (complex) forensic samples, and (cartridge) costs. Moreover, steps forward regarding ease-of-use and time-to-result will benefit the broader use of commercial rapid DNA systems. In fact, it would be a profit if rapid DNA systems could be used for full DNA profile generation as well as indicative analyses that can give direction to forensic investigators which will speed up investigations.

Abstract
Rapid DNA platforms are fully automated systems capable of processing DNA from biological samples and interpreting the results in approximately 90 minutes with minimal human intervention. With a greater reliance on the system than on the analyst, validation data are especially needed to define the performance and limitations of commercially available Rapid DNA systems. Thus, validation studies of a Rapid DNA workflow consisting of the Applied Biosystems RapidHIT ID Instrument and RapidLINK software with a focus on the ACE GlobalFiler Express Sample Cartridge and reference buccal swabs were performed in accordance with Scientific Working Group on DNA Analysis Methods Validation Guidelines. These validation studies included assessments of sensitivity, contamination, concordance, reproducibility and repeatability, stability, inhibition, mixtures, sample reprocessing, precision, and first-pass success rate. Overall, the current Applied Biosystems RapidHIT ID Instrument with the ACE GlobalFiler Express sample cartridge was found to be a reliable tool for generation of STR profiles from reference-type buccal swabs.

Abstract
The RapidHIT™ 200 device from IntegenX® provides a sample-to-profile platform that is capable of processing a variety of sample types. In this study we review the sensitivity of the 'Run Other' protocol for processing crime stain type samples containing various input quantities of DNA using the AmpFℓSTR® NGMSElect™ Express PCR Amplification Kit cartridges available from IntegenX®. The range of DNA inputs which achieved useable results were not as desired and therefore various enhancements to the instruments extraction processes were investigated. These studies showed an improvement in the range of DNA input templates that could by processed on the RapidHIT™ 200 by using the enhanced methods and resulted in three new run protocols.
