(a) The capacities of lysis buffer C (pH 4 to 10), and elution buffer Q (pH 9) for extracting DNA on DC, using the new protocol. (b). DNA electrophoresis of the related samples (Marker, *lyC4,5,6,7,8,9,10DC; *lyC and the number refers to lysis buffer C and the pH of lysis buffer C). (c) The OD260/OD280 (black) and OD260/OD230 (purple) purity ratios of the related samples. (TIF)</p
