Summary of "Vidéo 1 Extraction de l'ADN"
Methodology for DNA Extraction:
- Separation of Blood Components:
- Pour Blood Samples into tubes.
- Use a Centrifuge to separate plasma from blood cells.
- Aspirate the plasma.
- Destruction of Cell Membranes:
- Introduce a Saline Solution to destroy the Cell Membranes.
- Centrifuge for ten minutes to isolate Nuclei from cellular waste.
- Aspirate cellular waste and repeat Saline Solution introduction to ensure complete membrane destruction.
- Centrifuge for an additional five minutes to further separate Nuclei from waste.
- DNA Extraction:
- Freeze the sample at -80 degrees Celsius to destroy membranes and inactivate enzymes that could damage DNA.
- Thaw the sample in a water bath at 50 degrees Celsius.
- Introduce a Protein Solution to destroy the nuclear membrane.
- Place the solution in a shaker at 42 degrees Celsius overnight for optimal extraction.
