SARS-CoV-2 RNA Detection

COVID-19 PCR kits are used for the direct detection of the viral RNA in saliva or nasopharyngeal swab samples. These tests are highly accurate, using methods that amplify nucleic acids, such as reverse transcription (RT) polymerase chain reaction (PCR) and loop-mediated isothermal amplification (LAMP).

Rapid Isothermal PCR Kit


RayBiotech's COVID-19 Rapid Isothermal PCR Kit utilizes the RT-LAMP (reverse transcription loop-mediated isothermal amplification) method for the qualitative in vitro detection of SARS-CoV-2 nucleic acid. Results are read by eye within 30 minutes without the need for an expensive PCR instrument. The sensitivity is as low as 25 copies/µl of the virus. For increased stability, this kit contains reagents to reduce DNA carry-over contamination. It is also the only pH-independent kit on the market.

1-Step High Throughput PCR Kit


RayBiotech's COVID-19 1-Step High Throughput PCR Kit utilizes the RT-PCR (reverse transcription polymerase chain reaction) method for the in vitro detection of SARS-CoV-2 nucleic acid in saliva or nasal swab samples. The unique 1-Step Nucleic Acid Stabilization Buffer preps crude saliva or nasal swabs for use directly in the PCR reaction, without laborious RNA extraction steps. The sensitivity of this assay can detect as few as 4 copies/µL of SARS-CoV-2 virus. Only needing the green channel, this PCR kit can be used with a wide range of PCR instruments.

Product Features

  • No sample prep
  • Sensitive
  • Green channel only
  • CDC-approved primers
  • LDT ready
