Exfection™ Plasmid LE

Endotoxins (lipopolysaccharides, LPS) are present in the cell membrane of gram-negative bacteria, such as Escherichia coli. It is a common contaminant in plasmid preparations and can significantly reduce transfection efficiencies, if not removed during DNA preparations. GeneAll® Exfection™ Plasmid LE provides simple and fast method for the purification of plasmid DNA with low endotoxin contaminants.

Overview

Endotoxins (lipopolysaccharides, LPS) are present in the cell membrane of gram-negative bacteria, such as Escherichia coli

It is a common contaminant in plasmid preparations and can significantly reduce transfection efficiencies, if not removed during DNA preparations. 

GeneAll® Exfection™ Plasmid LE provides simple and fast method for the purification of plasmid DNA with low endotoxin contaminants. 

01

Format

Exfection™ Plasmid LE utilizes glass microfiber membrane.

  • Spin column format
  • Cell debris and salt precipitates are removed by centrifugation for mini kit and by EzClear™ Filter column for Midi kit
  • Midi kits require the centrifuge which has swing bucket rotor and ability of 4,000 x g at least..
02

High purity

  • Stable and consistent result
  • High yield and purity
  • Endotoxin level : <10 EU/μg
03

Simple and safe procedure

  • No phenol/chloroform extractions
  • No alcohol precipitation
04

Applications

  • Suitable for Cell transfection of most cell lines, enzymatic modifications, library construction, in vitro transcription/translation, high quality sequencing, cloning and most molecular biological experiments.
