Dry the DNA pellet at room temperature overnight or dry using a vacuum concentrator.Spin at max speed for 2 minutes, and carefully remove and discard supernatant.Wash the DNA pellet with 1 mL 70% EtOH (-20☌) and invert several times.Spin at max speed for 5 minutes and carefully remove and discard supernatant.Incubate the tube at room temperature for 15 – 30 minutes.

To precipitate DNA add 1 mL of 100% EtOH (room temperature), close tube and gently invert until DNA precipitate forms.

Spin at max speed for 5 minutes, and carefully transfer the upper aqueous layer to a fresh Eppendorf tube.

Thoroughly extract the samples with an equal volume of phenol/chloroform/isoamyl alcohol (25:24:1) and mix well by inverting the tube until the phases are completely mixed.

Simply expose cells to lysis buffer for 10 minutes at ambient.

Alternatively if a thermal mixer is not available, use a 56☌ water bath or heating block and vortex occasionally. Theres no need for any heating, centrifugation, or mechanical agitation steps for most samples. Incubate in a thermal mixer at 56☌ for 1 hour with agitation at 1400 rpm.Add 100 µL of cell lysis buffer ( see recipe) and 2 µL of 20 mg/mL proteinase K and mix by vortexing. Based on these results, the alkaline lysis buffer was higher efficient for rate of DNA amplification and ADO than with all other methods.Our advanced lysis and protease buffer system works with a variety of sample. Resuspend the cell pellet in 100 µL cold PBS and mix by pipetting up and down repeatedly. PCRBIO Rapid Extract Lysis Kit makes extraction of PCR-ready DNA quick and easy.Pellet cells by centrifugation at 1000 x g for 1 minute and discard supernatant.Sample Size: Start with 1 x 10 5 to 5 x 10 6 cells. The following is a sample protocol for the extraction of genomic DNA from cell culture.
