YALEPIC® Endotoxin Free Plasmid Midi DNA Isolation Kit(30-50ml) is intended for extraction from 30 ~ 50 ml of overnight bacterial cultures. It adopts anoptimized alkaline lysis method and features a unique silica membrane adsorption technology and special Buffer ER and Buffer YB for specific binding of plasmids and effective removal of endotoxins, proteins, and other impurities. The whole extraction process takes only 40 min. The extracted plasmid DNA contains minimal endotoxin residue (≤1 EU/μg) and can be used for the transfection of various types of cells and common experiments such as enzyme digestion, PCR, sequencing, and ligation.
