PCR Biosystems is committed to providing researchers, developers, and diagnostic kit manufacturers with the reliable PCR reagents they need for accurate and sensitive detection of the SARS-CoV-2 virus and its variants.

All products are manufactured according to ISO 13485 standards to meet (and exceed) the requirements for medical device components. And to support high-throughput diagnostic workflows, we’ve introduced 50mL and 500mL bulk sizes of our RT-qPCR mixes into our standard portfolio to provide greater consistency, convenience, and value in testing for COVID-19.

Products for Molecular Detection of SARS-CoV-2 Variants:

• qPCRBIO Probe 1-Step Virus Detect – A high-concentration 4x RT-qPCR kit designed specifically for ultra-sensitive, high-throughput detection of viral RNA sequences, including SARS-CoV-2. Enables users to add more sample to their reactions to boost analytical sensitivity, even when working with small volume reactions.


• RiboShield™ RNase Inhibitor – A recombinant protein that blocks the activity of a wide range of ribonucleases to reliably protect RNA from RNase digestion in all RNA-sensitive applications.


• qPCRBIO Probe 1-Step Go – A universal 2x master mix engineered for fast and sensitive 1-step RT-qPCR using sequence-specific probes. The redesigned buffer system, thermostable reverse transcriptase, and antibody-mediated hot start technology support rapid and accurate detection of the SARS-CoV-2 virus.


• UltraScript Reverse Transcriptase – A thermostable reverse transcriptase, producing high-quality cDNA ideal for a variety of downstream applications. The enzyme enables highly sensitive and accurate reverse transcription of viral RNA sequences, making it an ideal component of RT-qPCR-based SARS-CoV-2 detection tests.


• PCRBIO HS Taq DNA Polymerase & Mixes – Whether you need a hot start enzyme for high-throughput assays, automated reaction setup, or the detection of a low copy viral template, PCRBIO HS Taq DNA Polymerase is a robust, industry-leading enzyme to meet your needs.


• IsoFast™ Bst 1-Step Mix – A dual enzyme system for fast isothermal amplification of RNA targets in one step, without the need for specialized thermocycling equipment. 

We know there are enough challenges to be faced during a global crisis without having to worry about reagent supply. That’s why we massively scaled up the manufacture of critical reagents for rapid and sensitive virus detection.
