SARS-CoV-2 RNA Detection

COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Direct detection of the viral RNA can be performed using methods that amplify nucleic acids (Figure 1), such as reverse transcription (RT) polymerase chain reaction (PCR) and loop-mediated isothermal amplification (LAMP).

RayBiotech's COVID-19 Rapid Isothermal PCR Kit is suitable for the qualitative in vitro detection of SARS-CoV-2 nucleic acid.

Product Features

  • Rapid: Detect SARS-CoV-2 nucleic acid in 30 minutes
  • Affordable: No expensive PCR instrument required!
  • Easy to use: Read results by eye (see Figure 2).
  • Sensitive: Detects as few as 25 copies/µL of SARS-CoV-2 virus
  • Stable: Contains reagents to reduce DNA carry-over contamination. Only pH-independent kit on the market.

RayBiotech's COVID-19 1-Step High Throughput PCR Kit is suitable for the in vitro detection of SARS-CoV-2 nucleic acid in saliva or throat swab samples. Our unique 1-Step Nucleic Acid Stabilization Buffer preps crude saliva or throat swabs for use directly in the PCR reaction, without laborious RNA extraction steps.

Product Features

  • No sample prep: Use crude saliva or swabs directly. No RNA extraction needed!
  • Sensitive:Detect as few as 4 copies/µL of SARS-CoV-2 virus
  • Green channel only:Use it with a wide range of PCR instruments
  • CDC-approved primers
  • LDT ready for high complexity CLIA labs.
