1st BASE Viral DNA/RNA Extraction Kit

The kit allows for enhanced extraction of viral DNA/RNA (nucleic acid) from serum, plasma, body fluids, cell culture supernatant and viral transport medium swabs. This is a column-based extraction method that utilizes silica membrane spin column technology where the procedure involves lysis of viral cells, optimum binding of viral nucleic acid onto the silica membrane, washing and finally eluting viral nucleic acid from the silica membrane. The end-user is able to purify their viral DNA/RNA in less than 30 minutes. Product insert as attached.

A special feature of our kit is that it includes an inert carrier [poly-A] powder which enhances the binding of viral nucleic acid onto the silica membrane to improve its binding efficiency. It is an ideal kit to isolate low viral copies from 201 to 207 copies of viral nucleic acid. The purified viral nucleic acid is optimum for RT-PCR and qRT-PCR applications.

1st BASE 2019-nCoV Plasmid Positive Controls

The 2019-nCoV Plasmid Positive Controls are packaged for 500µL (200,000 copies/µL) in IDTE pH 8.0. This control will be ideal to existing COVID-19 screening users that are working on the E Sarbeco and RdRP genes. Each tube is sufficient for 2,500 duplicate reactions.

The product comes with one circular plasmid DNA, which contains partial sequences of 2019-nCoV E Sarbeco gene, RdRP gene and RNAse P gene.

As compared to our first version of positive control (Product No: MBS-4100) that was designed solely to be the positive control in Charité/Berlin qPCR protocol (version 17th Jan 2020), the version 2 of positive control includes new fragments of RdRP Helicase and human RNAse P for qPCR detection assay according to Chan JF-W et al., 2020 and CDC assays for SARS-CoV-2 detection respectively. Human RNAse P gene is regularly used as internal control (IC) for qPCR assay of SARS-CoV-2 detection.

Furthermore, we have introduced a pair of modified qPCR primers (Product No: CV013 and CV014) to detect RdRP gene using the same RdRP P2 probe in Charité/Berlin protocol. This resolves the assay sensitivity to better distinguish the signal between NTC and RdRP gene.

Next-Generation Sequencing Services for SARS-CoV-2 Genome 

As COVID-19 continue to spread, there is a need to decipher the SARS-CoV-2 viral genome. Routine testing methods such as qPCR are essential for viral detection however, they are unable to detect the mutational changes of the viral genome which is constantly evolving. Next-generation sequencing (NGS) provides an effective high-throughput solution for not just screening multiple samples but also for genome discovery projects.

Our high performance and reproducible SARS-CoV-2 genome sequencing service adopts a Targeted NGS approach with the ARTIC network panel and is a valuable tool to accurately sequence the SARS‑CoV‑2 genome for both detection and characterization of viruses. The service features and all-in-one package with a fast turnaround time. Just submit your total RNA and let us help you with the lab component while you focus on the science!
