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.

Features 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.
