Rapid, effective and low-cost purification of dideoxy-sequencing reactions by home-made magnetic beads suspension and magnetic separator.

ABSTRACT: Removal of excess dideoxy terminators from the sequencing mix after the enzymatic reaction is a key process affecting the dideoxy/Sanger sequencing quality. Ethanol precipitation may be the most popular clean-up method because of its low cost; however, it takes a long centrifugation time and frequently results in low quality sequence data. Commercially available clean-up kits provide high quality sequence data, while they generally have high cost. Here, we describe rapid, effective and low-cost dideoxy terminator clean-up method using a home-made magnetic beads suspension, MagNA, and magnetic separator. We found that MagNA enables rapid and efficient clean-up at ~1/100 of the cost of commercially available kits. The magnetic separator made using low-cost neodymium magnets worked well for t
