Why is the company Qiagen has more refined DNA extraction steps than a normal Strawberry DNA extraction practical? Summary of Qiagen DNA extraction steps Add ATL buffer and grind with sample. Add 20 microliters of enzyme Proteinase K to degrade protein into a 1.5-2ml microcentrifuge tube. Add 200 microlitres AL lysis buffer, and mix by vortexing for 5–10 seconds, which breaks cell membrane allowing DNA to be released. Incubate the sample at 56 degrees for 10 minutes. Mix the cell lysate with 200 microlitres ethanol by pipetting it at the side of the microcentrifuge wall so DNA precipitates. The DNA forms a white layer and the remaining liquid is discarded. Pipet the mixture into DNeasy Mini spin column placed in a 2 ml collection tube. Centrifuge for a minute at 8000 rpm. Place the mini spin column into a 2 ml collection tube, add 500 µl Buffer AW1, and centrifuge for 1 min at 8000 rpm. Then add it to a new 2 ml collection tube (provided), add 500 µl Buffer AW1, and centrifuge for 1…
DNA Extraction by Alkaline Lysis Procedure: 1. Spin 1.5 ml of cells in a microcentrifuge at maximum speed (12,000 rpm) for 20s to pellet. Remove the supernatant completely with a Pasteur pipet or a plastic pipettor tip. The spins can be performed at FC or at room temperature. Longer spins make it difficult to resuspend cells. 2 Resuspend pellet in 100pul GTE solution and let sit 5 min at room temperature. Be sure cells are completely resuspended. 3. Add 200ul NaOH/SDS solution, mix by tapping tube with finger, and place on ice for 5 min. 4. Add 150ul potassium acetate solution and vortex at maximum speed for 2s to mix. Place on ice for 5-15 min. Be sure mixing is complete. 5. Spin 3 min at 12,000 rpm to pellet cell debris and chromosomal DNA 6. Transfer 0.4 ml supernatant to a fresh tube, mix it with 0.8 ml of 95% ethanol or 0.4 ml isopropanol, and let sit 2 min at room temperature precipitate nucleic acids. 7.

4. Look at the gel image and answer the questions below and be specific. a) Based on your calculations of the DNA concentrations, how much DNA was loaded into each well? Do you see DNA for each of your samples? If not, why do you think that is so? b) Is the DNA in a single sharp band, multiple bands or a smear? What would each of these scenarios be due to, and why would you see them for your samples? c) Do you see multiple bands in your plasmid DNA sample? What are they?
Indicate true or false for the following statements The glycerol used in the DNA loading dye allows DNA to be visualized under UV light. The DNA Ladder used for agarose gel electrophores can be used to estimate fragment size and DNA concentration. During gel electrophoresis a DNA smear may indicate that DNase was still present in the sample.
