DNA Extraction/Genomic DNA Purification

The Presto™ Mini gDNA Bacteria Kit is a Bacteria genomic DNA extraction kit optimized for genomic and viral DNA purification from Gram negative bacterial cells and Gram positive bacterial cells. This Bacteria Genomic DNA Extraction Kit includes Gram+ Buffer and Lysozyme and when combined, will efficiently lyse bacterial cell walls consisting of the peptidoglycan layer. Chaotropic salt is used to lyse cells and degrade protein, allowing DNA to easily bind to the glass fiber matrix of the genomic DNA spin column. Contaminants are removed using a Wash Buffer (containing ethanol) and the purified genomic DNA is eluted by a low salt Elution Buffer, TE or water. The entire procedure can be completed within 30 minutes without phenol/chloroform extraction or alcohol precipitation. The purified DNA, with approximately 20-40 kb, is suitable for use in PCR or other enzymatic reactions.

The quality of the Presto™ Mini gDNA Bacteria Kit is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system. The purified genomic DNA from Escherichia coli cells (up to 1 x 109), (up to 40 µg with an A260/A280 ratio of >2.0) is quantified with a spectrophotometer and analyzed by electrophoresis.

Figure 1 .Genomic DNA (approximately 30 kb) was extracted using the Presto™ Mini Bacteria Kit. A Escherichia coli (1×109) culture (OD600=2, 1 ml) was harvested by centrifugation at 16,000 x g for 1 minute. A 5 µl aliquot of purified genomic DNA from a 100 µl eluate was analyzed by electrophoresis on a 1% agarose gel.
