Dead‐end hollow fiber ultrafiltration capture of environmental DNA for freshwater mussel (Unionidae) species detection with metabarcoding

Environmental DNA, Volume 5, Issue 6, Page 1148-1162, November 2023., 2023
Our study tested the use of dead‐end hollow fiber ultrafiltration (D‐HFUF) to concentrate environmental DNA (eDNA) from large volumes of environmental water (50‐L) for the detection of freshwater mussel species with DNA metabarcoding. We detected more species with eDNA captured with D‐HFUF than in eDNA samples captured with traditional polyethersulfone
