Additional description

Plasmid MiniPrep DNA Kit (Cat# 13300 )

For rapid and convenient plasmid DNA preparations

  • High yield of plasmid DNA
  • Purify plasmids up to 13 kb
  • Rapid spin-column format and 96-well format available
  • No phenol-chloroform extractions

Product Description

Norgen’s Plasmid MiniPrep Kit enables rapid analytical scale preparation of high quality plasmid DNA.The kit is able to purify plasmids up to 13,000 bp in size. Each column has a binding capacity of 25 µg, and the typical purification yield is up to 20 µg from 1.5 mL of bacterial culture.The purified DNA is free of genomic DNA, RNA and cellular proteins and is suitable for many downstream applications.

Purification is based on spin column chromatography. Briefly, thebacteriaharbouring the plasmidis pelleted and lysed, and the released plasmid DNA isbound to Norgen's column in the presence of Binding Solution (BIND).Under these conditions only the DNA will bindtothe columnwhilemost ofthe contaminating RNAand cellular proteinaceous componentsare removed in the flowthrough. The bound DNAis then washed to remove anyremaining impurities(WASH).Lastly, the purified DNA is eluted into 50 - 100µL of the provided ElutionBuffer or water(ELUTE).Pleaseseeprocedure flowchart to the right.

This kit is also available in a 96-well format for high-throughput plasmid purification.Purification with the 96-well plates can be performed using either a vacuum manifold or centrifugation.


  • Fast and easy processing - Rapid spin-column format allows for the processing of multiple samples in 30 minutes, while the 96-well plate can be processed in 35 minutes.
  • High binding capacity of columns - The binding capacity of the columns in the Plasmid MiniPrep Kit is 25 µg.
  • High yield- Up to 20 µg of plasmid DNA can be purified from 1.5 mL of bacterial culture.
  • Recovered plasmid DNA is suitable for downstream applications - Purified plasmid DNA is fully compatible withrestriction enzyme digestions, transformationsand sequencing.


Purified DNAis fully compatible with a wide range of applications including:

  • sequencing
  • transformation
  • restriction digestion

Figure 1.High DNA Yield from Small Cultures. Plasmid DNA from 1 mL overnight bacterial cultures was prepared with Norgen’s Plasmid MiniPrep Kit and compared with two other commercial kits.The purifications were performed in triplicate, and the average yield for each kit is shown in the graph. The quantification of the DNA yield was performed by resolving 5 µL of the 50 µL of eluted DNA on a 1X TAE, 0.9% agarose gel followed by densitometry. Norgen shows a significantly higher average yield than the other 2 competitor’s kits.

Figure 2.High-Accuracy Sequencing. One microgram of plasmid DNA purified by Norgen’s Plasmid Miniprep DNA Kit was used as a template in an Applied Biosystem DNA Sequencer. The result showed an accuracy of >99% over a 950 bp contiguous sequence.
