Taller 'Extrae tu propio ADN'

Extract Your Own DNA Workshop

Introduction to the Workshop

• The speaker introduces themselves as a technical service researcher from the University of Seville, focusing on a workshop titled "Extract Your Own DNA."

• The goal is to extract personal DNA using saliva and common household products.

Materials Needed

• Essential materials include:

• Approximately 120 milliliters (4 tablespoons) of water.

• A small amount of salt (half a tablespoon).

• Liquid detergent and 96% alcohol for the extraction process.

Preparing the Sample

• Participants are instructed to prepare their saliva sample by chewing inside their cheeks to stimulate salivation.

• Once enough saliva is collected, it should be spat into a separate container for mixing with the prepared solution.

Mixing Ingredients

• After combining water and salt, participants are advised to mix gently without creating bubbles or foam.

• Alcohol should be added cold (preferably from the freezer), which helps precipitate dissolved DNA molecules at the interface between water and alcohol.
