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.

Does RiboGrip help with inhibitor resistance?

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