OVERVIEW VIRUS DETECTION DATA ANALYSIS ORDERING AND SPECS RESOURCES
OVERVIEW

The recent Coronavirus pandemic has led to a rapid response from the viral research and therapeutics community around the world. These research teams need robust and reliable genomic tools to classify and characterize viral samples. Twist offers Research-Use Only (RUO) NGS target enrichment panels for the detection and characterization of SARS-CoV-2 virus. The panel targets about 30 kb viral genome with approximately 1,000 probes, designed against the SARS-CoV-2 genome (GenBank: MN908947.3).

VIRUS DETECTION

NGS for Virus Detection

Next-generation sequencing (NGS) offers high-throughput, specific identification of infections in a variety of sample types including blood, nasal swab, feces, etc. In the case of viral infections, however, direct sequencing can be a challenge due to the extremely low concentration of the viruses of interest and the presence of high background from the host. Target capture using DNA-based hybridization probes to isolate specific sequences out of a mixed genomic sample can increase the sensitivity and specificity of NGS-based efforts.

High Sensitivity Through Efficient Design

Twist’s highly sensitive and accurate target capture enables efficient viral RNA detection. We demonstrate target enrichment’s ability to capture and detect the viral genome at varying numbers of viral copies spiked into human reference RNA. At high viral load (approximately 1 million copies), the complete genome is recovered even with only 25,000 reads. While at lower copy numbers, coverage of large portions of the viral template is maintained. No reads from the negative control map to the viral template even when using 8 million mapped reads, demonstrating our detection at 10 copies represents true capture and not background contamination. Find out more in the App Note.

DATA ANALYSIS

Biotia Analysis

Twist SARS-CoV-2 Research Panel has been combined with additional reagents and analysis to create an end-to-end solution from sample collection through tertiary analytics, providing the SARS-CoV-2 NGS Assay.

The Biotia COVID-DX (v1.0) software provides a research-oriented report that includes the full sequence of the SARS-CoV-2 virus, enabling improved understanding of mutations, genetic variations, and the evolution of the virus as it is transmitted. FASTQ files (sequencing output) can be generated in laboratories and submitted to Biotia COVID-DX (v1.0), a cloud-based software, to generate research-use only reports. The purchase of each SARS-CoV-2 NGS Assay kit includes credits for COVID-DX (v1.0) bioinformatic analysis of each sample. 

To receive Biotia analysis credits, simply register through the Biotia User Portal via www.biotia.io and enter the unique order number emailed to you once you place your order. These credits provide access to run samples through the report generation component of the software.

Genetic variants identified

Genetic variants are determined by aligning the test strain to the SARS-CoV-2 reference genome (NC_045512.2) with information on gene location/site, alteration and literature notes if any.
