Web15 aug. 2011 · Plasmid DNA minipreps are fundamental techniques in molecular biology. Current plasmid DNA minipreps use alkali and the anionic detergent SDS in a three-solution format. In addition, alkali minipreps usually require additional column-based purification steps and cannot isolate other extra-chromosomal elements, such as bacteriophages. WebMonarch Plasmid Miniprep Kits provide fast and reliable purification, reduced hands-on time and elution in low volumes. Our unique column design offers several improvements over other commercially available products, including the elimination of buffer retention, and elution in as little as 30 µl.

WebDiscard the flow through into your miniprep waste container, it should not go with other liquid waste. Remember to follow proper disposal protocols. Your plasmid DNA should now be bound to the silica column. Wash the silica spin column by adding 500 μl Buffer PB Wash Buffer 1 and centrifuging for 60 s. Discard the flow-through into miniprep waste. WebMonarch miniprep buffers are color coded for your convenience. DON’T let the tip of the column touch the flow-through in the collection tube after washing Ethanol can carry over from the collection tube to the column tip. Ethanol in your eluate can interfere with downstream applications.
