  • Safe – No phenol/chloroform extractions
  • Versatile – Spin and vacuum formats available
  • High-quality – Endotoxins efficiently reduced (<1 EU/µg)

Product has been discontinued in 2024 and has been replaced by D6950 E.Z.N.A.® Endo-Free Plasmid DNA Mini II Kit.

Plasmid isolated with traditional purification procedures normally contains high levels of endotoxins (also known as lipopolysaccharides or LPS) that can significantly interfere with transfection experiments downstream. Up to 5 mL of overnight cultures can be used for high copy number plasmids and 10 mL for low copy number.

The E.Z.N.A.® Endo-Free Plasmid DNA Mini Kit I integrates an efficient endotoxin removal step into the plasmid purification procedure to produce high-quality transfection grade (<1 EU/µg) plasmid for efficient transfection. The bacterial cells are lysed using the alkaline-SDS lysis method. The cleared cell lysate is then treated with ETR reagent to efficiently remove the endotoxins. After adjusting the binding conditions, the cell lysate is applied into the HiBind® DNA column and purified DNA is eluted from the column membrane.

For Research Use Only. Not for use in diagnostic procedures.

Figure 1.  Quality and yield of plasmid DNA purified using the E.Z.N.A.® Endo-Free Plasmid DNA Mini Kit. Plasmid DNA was isolated from 3 mL of 3 different bacterial cultures. DNA was eluted in 100 µL endotoxin-free elution buffer and quantitated using Thermo Fisher’s NanoDrop® 2000 and dynamic turbidity method.
