Instead of optimizing the bind, wash, and release steps in conventional silica-based spin purification preps, the technology focuses on a separation by performing a single step fractionation based on the size of the biomolecules, which results in depleted impurities.

General description
GenElute™-E purification kits provide a simple alternative for DNA purification. Compared with traditional methods, GenElute™-E offers:
Traditional silica-based, bind-wash-elute purification kits require multiple wash steps to remove impurities from the spin columns. These steps increase the risk of cross contamination, subject the DNA to centrifugation sheering forces, and introduce chaotropic salts that can carry over into the final sample, inhibiting downstream applications.
GenElute™-E kits employ size exclusion negative chromatography to separate large nucleic acid molecules from smaller protein, lipid, and ionic components in cell, tissue, blood, and other samples. Single-spin columns efficiently absorb and retain cellular debris and sample contaminants while allowing nucleic acids to pass through, reducing the number of steps and plastic materials required for purification. This novel method for high-quality purification is made possible by our innovative SmartLyse® Protease, which enables fast and efficient lysis of a wide range of sample types.
Isolate nucleic acid in a fraction of time compared to traditional silica bind-wash-elute procedures. Simply mix sample with lysis components and incubate according to kit protocol, pipette sample onto the spin column, and centrifuge directly into a collection tube. Cellular debris and contaminants remain bound in the column to be discarded, while purified DNA is ready to be used in downstream applications or stored.
- Isolation of DNA in under an hour with minimal sample handling
- Better purity, leading to improved performance in PCR and other applications
- Significant reduction in plastic and hazardous chemical waste

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is aligned with "Waste prevention" and "Designing safer chemicals". Click here for more information.
Application
The GenElute™-E Cap Puncher is designed to work with the GenElute™-E line of DNA and RNA purification kits. When pressed onto the lid of the single-spin column, the cap puncher creates a small opening through which a sample can be pipetted directly onto the column. This reduces the amount of handling by eliminating the need for cap removal, and lessens the chance of cross contamination when handling multiple samples.For full instructions, please reference any of the GenElute™-E protocols.
Other Notes
We believe that green chemistry will contribute to a better tomorrow. With a growing portfolio of greener alternatives, there are now more choices to reduce the ecological impact of your research while still delivering quality and efficacy so your results are not compromised. GenElute™-E purification kits avoid the use of hazardous wash buffers typically employed in silica-based purification kits, significantly reducing chemical waste. The single-spin protocol also limits the number of collection steps, reducing plastic waste. GenElute™-E is designated a Greener Alternative Product based on the "Prevention" and "Designing Safer Chemicals" qualifications of The 12 Principles of Green Chemistry.GenElute™-E kits also adhere to the principles of SMASH Packaging, our global initiative to improve the sustainability through the reduction of packaging materials, the increased use of sustainable alternatives, and improved recyclability. Packaging is FCS-marked for sustainable forestry practices and produced from greater than 70% recycled content.

Genelute-e single spin DNA and RNA purification kits use negative chromatographty to isolate nucleic acids. Can you explain how this approach simplifies workflows?

Does the technology introduce any bias into the sample?
1 answer-
GenElute™-E does not introduce biases that some “bind-wash-elute” technologies can add because the technology separates by size, rather than by what binds and what is released.

What is the composition of the lysis buffer and clearing buffer after flowing through the resin?
1 answer-
The presence of EDTA, SDS, or excess salt can affect my PCR/ sequencing reaction. The lysis buffer information is proprietary, but we can say it is free of chaotropic salts. The resins are desalting resins so EDTA, SDS, and salts are depleted.

Do we know how stable the purified DNA is through several freeze-thaw cycles?
1 answer-
This will fluctuate due to sample variability (sample collection, concentration, fragment length, sequence [GC content], storage before isolation, etc.). However, the sample is buffer exchanged into a standard storage buffer that is included in the kit (1X TE).
