Product Description


  • Rapid protocol - Isolate DNA from microbial cultures in just 20 minutes
  • Isolate pure, high-quality DNA - Ready to use in PCR, qPCR, restriction digests, Sanger sequencing and NGS
  • Optimized lysis method - Mechanical lysis via bead-based homogenization enables isolation of DNA from yeast, fungi, Gram-negative and Gram-positive bacteria

The DNeasy UltraClean Microbial Kit is designed to isolate high quality genomic DNA from 1.8 ml of microbial culture. A variety of microorganisms including Gram-negative and Gram-positive bacteria, yeast, and bacterial and fungal spores have been tested successfully with this kit. The microbial cells are added to a bead beating tube containing beads, bead solution and lysis solution. The principal is to lyse the microorganisms by a combination of heat, detergent, and mechanical force using an optimized bead beating tube. The cells are lysed using our specially designed Vortex Adapter on a Vortex Genie 2 Vortex. The released DNA is then bound to a silica spin filter, washed and the DNA is recovered in certified DNA-free Tris buffer. 

For isolation of microbial DNA using a bead-based homogenizer, try our DNeasy PowerLyzer UltraClean Microbial Kit.

Review by E.M. / (Posted on 11/12/2015)

<p style="text-align: justify;">I received the sample and used it to prep gDNA of <em>B. subtilis</em>, getting great yield and quality DNA on the first try. I used the samples for whole genome sequencing and received perfect quality scores from start to finish. So, all in all I am very happy with the product and will make sure to mention it in the methods of the eventual paper from this research. It might be a while before we order as we only very rarely require gDNA, but I will recommended it to my lab for the next time. We had been doing messy phenol/chloroform/iso-amyl alcohol extractions before now!</p>
