Endotoxin-free plasmid DNA maxipreps—NucleoBond Xtra Maxi EF/Maxi Plus EF

Transfection-grade plasmid purification kits

NucleoBond Xtra EF kits use anion exchange and gravity flow for purification of endotoxin-free plasmid DNA, Endotoxin removal is achieved in a unique washing step—no extra incubations are necessary. Lysates are cleared by simple filtration using the included special column filter, designed for high filter flow rates and rapid lysate clearing—no centrifugation is required.

NucleoBond Xtra EF kits use anion exchange and gravity flow for purification of endotoxin-free plasmid DNA, Endotoxin removal is achieved in a unique washing step—no extra incubations are necessary. Lysates are cleared by simple filtration using the included special column filter, designed for high filter flow rates and rapid lysate clearing—no centrifugation is required. Additionally, NucleoBond Xtra has improved silica material with higher binding capacity, leading to typical yields of 400 μg (Midi) and 1000 μg (Maxi). 

NucleoBond Xtra Finalizers: The finalizers, provided with the Plus kits, replace the time-consuming centrifugation step that follows every isopropanol precipitation of diluted DNA samples.

Overview

  • Xtra fast—reduce prep time by up to 68% (103 minutes for Maxi EF and 48 minutes for Maxi Plus EF)
  • Xtra high yields—obtain up to 100% more transfection-grade plasmid DNA. Typical yield: up to 1,000 µg
  • Xtra efficient endotoxin removal—obtain DNA with less than 0.05 EU/µg
  • Xtra flexible—available with or without the NucleoBond Finalizer (for ultrafast purification)
