📍 Water Management: To minimize contanimation, use Sigma W4502-1L water for all steps (Master Mix, TE’ dilution, and PCR make-up volumes).
Aliquot 10 mL in 15 mL tubes Aliquot 1 mL in 1.5 mL tubes Store at 4°C

🧪 2 M Tris, pH 8.3 Stock

1. Remove 23 ml from a '100 ml' bottle of Water (Sigma W3513).
  Note: this leaves ~80 mL.
2. Add 27 g Trizma pH 8.3 crystals (Sigma T8943).
3. Shake until dissolved. (Density: 1.0718 g/ml).

🧪 100X TE' Preparation

1. Remove 10 ml from 100 ml bottle of 1 M Tris, pH 8.0 (T2694).
2. Add 10 ml 100X TE (Tris/ EDTA: T9285).
3. Result: 1M Tris / EDTA.

🧪 1X TE' Working Buffer (Tris, EDTA)

• Dilute 100X TE' 100-fold using Sigma W4502 water.
• Formula: 10 ml of 100X TE' + 990 ml Water.
• Use for diluting primers and all nucleic acids.
