These kits are designed for the rapid spin column removal of endotoxins from previously purified DNA. Norgen’s spin columns bind DNA while endotoxins, salts and other contaminants are washed away. These kits reduce endotoxins to 0.1 EU/μg DNA or less providing plasmid DNA that is immediately ready for transfections or other endotoxin-sensitive applications. Typical recovery of DNA is >90% of the starting sample.
Endotoxin Removal Kit (Mini)
This kit is designed for the rapid spin column removal of endotoxins from up to 25 µg of previously purified DNA. The convenient spin column procedure can be completed in approximately 20 minutes.
Endotoxin Removal Kit (Midi)
This kit is designed for the rapid spin column removal of endotoxins from up to 200 μg of previously purified DNA. The convenient spin column procedure can be completed in approximately 30 minutes.
Endotoxin Removal Kit (Maxi)
This kit is designed for the rapid spin column removal of endotoxins from up to 1 mg of previously purified DNA. The convenient spin column procedure can be completed in approximately 30 minutes.
About Endotoxins
Endotoxins (also called lipopolysaccharides), are cell-membrane components of Gram-negative bacteria such as E. coli. Endotoxins are released during the lysis step of plasmid purification and significantly reduce transfection efficiencies in endotoxin sensitive cell lines. Therefore, the removal of endotoxins from plasmid preparations is often necessary prior to the use of the DNA in such downstream applications.

The kit offers the unique feature to isolate total RNA including small RNA and DNA from serum and plasma without the need to resort to the cumbersome phenol/chloroform extraction or a time consuming proteinase digest. RNA purified using the kit is ready for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

This product is based on the purification method of high binding magnetic particles. The sample material is denatured in Lysis Buffer. The protein is then precipitated by Protein Precipitation Solution and pelleted by centrifugation. After adding magnetic particles and binding solution, RNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption.The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally RNA was eluted by Elution Buffer.

Storage and Stability
MagPure Particle N should be stored at 2–8°C upon arrival. However, short-term storage (up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions.

Heat-Labile Exonuclease I (HL-ExoI) is a 3’ – 5’ exonuclease, specific for single stranded DNA. The enzyme is recombinantly produced in E. coli. HL-ExoI is active at 25 – 37°C and inactivated by 1 minute incubation at 80°C or 15 minutes at 60°C.
HL-ExoI is used for degradation of ssDNA such as primers and oligos. It is also ideal for treatment of sensitive samples and useful in the development of novel molecular diagnostics applications.
