Express barcoding with NextGenPCR and MinION for species-level sorting of ecological samples
O_LIDNA barcodes are useful for species-level sorting of specimen samples, but rarely used in time-sensitive projects that require species richness estimates or identification of pest or invasive species within hours. The main reason is that existing express barcoding workflows are either too expensive or can only be carried out in very well equipped laboratories by highly trained staff. C_LIO_LIWe here introduce a simple workflow that combines rapid DNA extraction with HotSHOT, amplicon production with the aid of NextGenPCR(R) thermocyclers, and sequencing with low-cost MinION sequencers. C_LIO_LIWe demonstrate the power of the approach by generating and identifying 250 barcodes for 285 specimens within 6 hours. The workflow only required the following major equipment that easily fits onto a lab bench: Conventional thermocycler, NextGenPCR(R) thermocycler, microplate sealer, Qubit, and MinION. C_LIO_LIWe argue that species-level sorting with simplified barcoding workflows is now faster, more accurate, and sufficiently cost-effective that it can and should replace morphospecies sorting in many projects.
