Vidéo 1 Extraction de l'ADN

Methodology for DNA Extraction:

1. Separation of Blood Components:
   • Pour Blood Samples into tubes.
   • Use a Centrifuge to separate plasma from blood cells.
   • Aspirate the plasma.
2. 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.
3. 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.
