Acetic Acid (mw: 60.05 g/mol)59.955 g1 M
  1. Prepare 800 mL of dH2O in a suitable container.
  2. Add 242 g of Tris base to the solution.
  3. Add 18.61 g of Disodium EDTA to the solution.
  4. Add 59.955 g of Acetic Acid to the solution.
  5. The 1x TAE solution is 40mM Tris, 20mM Acetate and 1mM EDTA and typically has a pH around 8.6 (do not adjust).
  6. Add dH2O until the volume is 1 L.
