YALEPIC® Endotoxin Free Plasmid DNA Maxi Isolation Kit (PLUS) (100-300ml) is suitable for extraction from 100 – 300 ml of bacterial solution cultured overnight, using an improved SDS-alkaline lysis method to lyse the bacteria. The PB solution contains indicators that can indicate whether the lysis and neutralization are complete through the change of color, so as to ensure the quality of plasmid extraction and visualize the operation. A newly developed endotoxin removal solution YEB and separated by centrifugation to remove endotoxins reducing endotoxin levels to as low as 0.1 EU/μg. The purified DNA is suitable for a variety of molecular biology applications including restriction enzyme digestion, ligation, transformation, DNA sequencing, and transfection.
