1copy™ COVID-19 qPCR Multi Kit



1copy COVID-19 qPCR Multi Kit qualitatively detects E gene and RdRp gene of COVID-19 via real-time qPCR using reverse transcriptase and RNA extracted from nasopharyngeal and oropharyngeal swab specimens of patients suspected of respiratory disease. With significantly high accuracy and low LoD, the limit of detection, 1copy™ COVID-19 qPCR kit not only has a short total testing time but is also very convenient due to the combination of reverse transcription and amplification into a single step.


1copy™ Probe Technology

1copy™ Probe, the core technology of 1drop Inc. molecular diagnostics, is a chimeric probe composed of DNA and RNA, and its degradation efficiency is increased by the endonuclease activity of our specially designed RNaseHII6, allowing for higher fluorescence intensity and consequently, a more accurate quantification. RNaseHII6 is specifically developed to be strongly resistant to heat and is therefore optimized for hot-start PCR, allowing for a higher probe degradation efficiency. With this unique technology, 1copy™ Probe can stably and accurately detect mRNA at the single-molecule level.


High Sensitivity

Because 1copy COVID-19 qPCR Multi Kit is able to detect even a single molecule of viral RNA, risks of asymptomatic Covid-19 patients spreading the virus significantly lessen.
