Reagents Provided
Item Pcs. Vial size
40x One-step SOLIScript® CoV Mix 1 250 rxn | 125 µl

Water, nuclease free 1 5 ml


SOLIScript® 1-step CoV Kit is optimized for highly sensitive detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral RNA by one-step real-time RT-PCR (RT-qPCR).

The Kit is suitable for the detection of up to four targets simultaneously and can be used with all common qPCR cyclers. Follow recommendations specific for a selected SARS-CoV-2 diagnostic panel, and instrument-specific guidelines. Contact us if a passive reference dye is required for signal normalization.

SARS-CoV-2 primers and probes, applicable positive and internal extraction controls are not provided with the Kit and should be supplied by the user.

SOLIScript® 1-step CoV Kit is tested and validated for SARS-CoV-2 detection by diagnostic laboratories. Please see our recommendations for US-CDC and Berlin-Charité protocols. 

Note! Amplification of more than one target in a single reaction may require considerable optimization, individual assays must be validated prior to multiplexing. For multiplex reactions, design primer pairs with similar annealing temperatures for all targets to be amplified. Self-complementarity of primers should be avoided.

Does RiboGrip help with inhibitor resistance?

RiboGrip™ is not directly associated with tolerance to common inhibitors, however, it helps to keep RNA intact because RiboGrip inhibits Rnase H.

Which primes, probes are recommended for COVID-19 detection with Your 1-step kit?

The Kit has been tested and validated by diagnostic laboratories using primer-probe panels recommended by Charité, (Germany) and CDC (USA) protocols according to WHO “Coronavirus disease (COVID-19) technical guidance: Laboratory testing for 2019-nCoV in humans”, section: “Molecular assays to diagnose COVID-19”; subsection: “In-house developed molecular assays”

Are primers, probes and positive control included in the 1-step RT-qPCR CoV kit?

SARS-CoV-2 primers and probes, applicable positive and internal extraction controls are not provided with the Kit and should be supplied by the user.

Why do certain kits contain a ROX?

ROX (carboxy-X-rhodamine) is one of the passive reference dyes providing a constant fluorescent signal that is used for signal normalization during the amplification cycles. The emission recorded from a reference dye during the baseline cycles is used to normalize the emission recorded from the reporter (e.g. EvaGreen®, SolisGreen®, SYBR® Green, etc.) in later cycles in ROX-dependent real-time PCR systems (e.g. Applied Biosystems 5700, 7000, 7300, 7700, 7900HT, StepOne™, StepOnePlus™). Reference dye compensates for small fluorescent fluctuations and well-to-well variations that may occur.

In Solis BioDyne qPCR mixes we use technology, based on ROX, that allows us to use same mix for high- and low- ROX requiering cyclers. 

Please check cycler-mix compatibility here if not sure.

Custom Solutions?

Need something custom and out-of-the-box? Your needs are our priority. To ensure quick development and go-to-market time you can leverage our dedicated support and development throughout the process. Please contact us if you have a specific requirement but cannot find the best solution among our catalog products. We may be able to offer you bulk products, tailored product sizes, and formats, or specific formulations. We are flexible and dedicated to meeting your needs!

Quality has always been the core value of our work. To ensure we match the high-quality requirements of our partners in the research and diagnostic sector, we implemented the ISO 13485 standard in 2018 to complement the ISO 9001 certificate we acquired in 2007.


Strategic cooperation with the Solis BioDyne team has been one of the most efficient we have experienced during our COVID-19 diagnostic kits products development. Their room temperature stable master mix is an excellent product that has helped us to reach higher sensitivity and stability of our qPCR diagnostic kits. 

Chief Operating Officer at MultiplexDX

We chose SOLIScript 1-step CoV kit for SARS-CoV-2 wastewater screening project because we anticipated difficulties in the global supply chain and we already had experience with Solis BioDyne products. In addition, we believe in using local suppliers when possible and reducing our ecological footprint.
