1copy™ Probe, one of 1drop's key technology, is a DNA-RNA hybrid probe that is used with a thermally stable enzyme, RnaseH, suitable for hot start technique to maximize the degradation efficiency. As a result, fluorescence emission is increased significantly which allows detection of DNA and RNA at the level of a single molecule.

1copy™ uses a DNA-RNA-DNA hybrid probe with thermally stable RNaseH to provide stable and reproducible results to accurately quantitate genetic material.
Because 1copy™ can detect target genes in a single step, it is quick and simple to use.
1copy™ is compatible with many PCR machines used worldwide.
1copy Probe provides consistent performance of detecting at a single molecule level.

With 1copy™ Probe technology, detection at a single molecule level is not only possible but also applicable to many different fields that require highly sensitive technology.
