Introduction:

TAE buffer (Tris- Acetate -EDTA Buffer) is a commonly used DNA electrophoresis buffer, commonly used in agarose gels, less used for PAGE gels. When the resolution requirement of electrophoresis is not high, both TAE and TBE can be used. When the resolution requirements are relatively high, TAE is suitable for electrophoresis of lower concentration gels to improve the resolution of large molecular weight nucleic acids, and on the contrary, TBE is used to improve the resolution of small molecular weight nucleic acid with the use of higher concentration gels.

This product is a pre-mixed powder: no need to weigh or adjust the pH value, each pack can be directly dissolved and mixed into a 1 L 50× storage solution. It must be dissolved in distilled water or deionized water to prepare 1× or 0.5× working concentration according to specific experimental requirements before use.

Storage: Store at room temperature for 24 months.

Protocol (for reference only):

1. Prepare 50×TAE from powder

1. Fill a graduated cylinder or beaker with approximately 700 mL of distilled water and place a magnetic stir bar into the container.
2. Place the container on a stir plate and slowly add the contents of 1 package of 50× TAE to the water.
3. Mix the solution until the TAE is completely dissolved, then add distilled water to bring the final volume to 1 L.

2. Prepare 1× TAE: Dilute 20 mL of 50× TAE with 980 mL of deionized or distilled water. Label as 1× TAE.
3. Prepare 0.5× TAE: Dilute 10 mL of 50× TAE with 990 mL of deionized or distilled water. Label as 0.5× TAE.
