Plasmid Maxiprep Purification Kit provides a unique Maxi-column and a high efficiency lysis buffer system to yield up to 800 μg high purity plasmid DNA from 100 to 400 ml bacterial cultures. The system containsendotoxin-removal reagent to eliminate eondotoxins. The high-purity plasmid DNA eluted using Plasmid Maxi Purification Kit is suitable for performing transfection experiments.


  • Easy and Fast: Centrifugation and wash can be done in 50 ml centrifuge tube.
  • Safe: Does not require phenol/chloroform or CsCl/ ethidium bromide gradient centrifugation.
  • High Purity: Unique endotoxin removal formula, plasmid DNA purified can be used to perform sequencing, transfection or other experiments.
  • High Yield:  About 200~800 µg plasmid DNA can be purified from each reaction,  which is higher than the usual ion exchange method used by other suppliersbrands.

Experimental Data

Test 1

Plasmid Maxiprep Kit yield and stability test

Purification of 4.6 kb plasmid DNA from 120 ml of E. coil using Plasmid Maxiprep Purification Kit.
The plasmid DNA was eluted with 1.5 ml of Elution buffer and analyzed using 0.8% agarose gel electrophoresis.
