The purity and concentration of the extracted plasmid DNA can be detected by agarose gel electrophoresis and an ultraviolet spectrophotometer. An OD260 value of 1 corresponds to approximately 50 μg/ml of double stranded DNA. The OD260/OD280 value of the purified plasmid DNA is generally in the range of 1.7-1.9. The purified plasmid DNA can be directly applied to experiments with high purity requirements, such as cell transfection or in vivo experiments.

The EndoFree Maxi Plasmid Kit adopts a unique silica membrane adsorption technique to efficiently and specifically bind plasmid DNA. By combining the special Endotoxin Removal Buffer P4 and EndoFree Maxi Filtration Columns, endotoxin, proteins and other impurities can be effectively removed. The whole extraction process takes only 1 hour, ensuring the convenient and quick operation.
Recommended bacteria amount for each practice: For high-copy plasmid, it is recommended to use 100 ml of bacteria culture media, and the yield from which is generally around 500-1500 μg. For low-copy plasmid, 200 ml bacteria culture media is recommended to generate around 200-600 μg plasmids.
