What makes the PureLink Expi Endotoxin-Free Mega/Giga plasmid purification kits yield endotoxin-free plasmid DNA?
The anion exchange resin used in PureLink HiPure plasmid purification kits produce plasmid DNA with inherently low endotoxin levels of 0.1-1.0 EU/µg. To add to this, PureLink Expi Endotoxin-Free Mega/Giga plasmid purification kits contain endotoxin-free components, and a proprietary Endotoxin Removal Buffer that further enhances endotoxin depletion, resulting in plasmid DNA that is consistently endotoxin-free (< 0.1 EU/µg) .
