Monarch pcr dna cleanup kit 5 µg protocol monarch pcr dna cleanup kit 5 μg performs equivalently to the leading supplier preps were performed according to recommended protocols. Gel purification is most efficient with lower agarose gels so you will want to stay in the 0 7 0 8 range if possible. Buffer dp3 for qiagen directprep 96 well miniprep 3 0 m ammonium acetate ph 5 5.

You will want nice crisp bands. Follow the agarose gel electrophoresis protocol with the following amendments. Pretreatment for gram positive bacteria. One microgram of purified dna was used to prepare oxford nanopore technology ont sequencing libraries following the ont 1d ligation sequencing kit sqk lsk109 protocol without dna fragmentation.

This protocol is designed for purification of total dna from gram positive bacteria. If the plasmid dna is of low yield or low in quality the samples can be analyzed by agarose gel electrophoresis to determine at what stage of the purification procedure the problem occurred.
