Learn how to use this product The new DCU PCR Clean-up protocol enables the fast and efficient recovery of low-quality DNA samples and the purification of post-PCR samples ready for use in sequencing and other applications. It is an all-in-one method that does not require columns, gel extractions, or additional solvents. The Isohelix DCU DNA CleanUp Kit is a valuable supplementary purification step that takes less than 30 minutes to fully reclaim low-purity samples without sacrificing yield. It prevents costly retesting and the waste of valuable laboratory time.
