New research at COPAN Group has led to an important technological breakthrough in the yield of target nucleic acid from its FLOQSwabs. In the case of Low Copy Numbers (LCN) when minute quantities of nucleic acid might be present in a sample, maximum yield of nucleic acid can make the difference between a positive or negative result.

Even though FLOQSwabs release almost the entire sample, nucleic acid has a tendency to be sticky and some residue can still attach to swab fibers. This risk is eliminated with COPAN’s latest discovery in fiber treatment for flocked swabs. COPAN’s high nucleic acid yield FLOQSwabs now deliver as much as 1 log more nucleic acid, equivalent to 3 PCR cycles less for detection. This is another milestone in the evolution of flocked swab technology and ensures the maximum sensitivity of assay. The recent discoveries are now the subject of a series of new patent applications by COPAN in the US and in other countries around the world.
