Includes: illustra bacteria genomicPrep Mini spin columns prepacked with novel silica membrane; Lyophilized proteinase K powder; Lysis solutions, wash and elution buffers; 2mL Microcentrifuge collection tubes; a full booklet with a detachable, quick reference protocol card



The illustra Bacteria genomicPrep Mini Spin Kit can be used with a wide range of bacterial strains such as DH5a, TOP10, JM109, Bacillus subtilis etc. The kit produces highly pure and intact genomic DNA with OD260/280 values of 1.75-1.85. Use different elution volumes to isolate genomic DNA at concentrations suitable for most downstream applications including restriction enzyme digestion, RT-PCR, and long PCR.

The method uses a lysis solution in combination with proteinase K to gently release genomic DNA into solution from bacteria cells. The DNA is deproteinated in the extraction solution and the genomic DNA is then bound onto a silica column in the presence of chaotropic solution. Contaminants are removed during wash steps and the purifed DNA is eluted with prewarmed TE solution.

  • Total DNA extraction time under one hour with reduced lysis time
  • Can be used to purify 4 to 8µg of genomic DNA from 2 x 109 bacteria cells with input amounts ranging from 1 x 109 to 4 x 109 bacteria cells
  • Spin columns prepacked with a silica membrane—provide excellent reproducibility and consistency
  • Validated in several downstream applications including RT PCR, long PCR, and restriction digest
  • Color-coded caps for ease of use
