DRIED BLOOD SPOT-BASED TRACE DNA EXTRACTION METHOD

摘要

A dried blood spot-based trace DNA extraction method, comprising: preparing a high-efficiency liquid-phase separation tube; collecting a DNA solution and then mixing same with 100 ng of a carrier RNA; adding an equal volume of phenol chloroform, and transferring same into the high-efficiency liquid-phase separation tube; performing high-speed centrifugation to perform liquid-phase stratification; and recovering 98% of a supernatant.
