TES sodium salt is a commonly used zwitterionic buffering agent in the field of biochemistry, commonly known as 2- [(tri (hydroxymethyl) amino] -1-ethanesulfonic acid sodium. CAS number 70331-82-7 has a white powder appearance and produces a colorless and transparent solution when dissolved in water. TES sodium salts have a wide range of applications in biological research, but cannot be used for Folin protein determination.

1. Buffer interval. The pH range of TES sodium salt is 6.8-8.2. At room temperature, the pKa value is 7.5, and it has good buffering ability in the pH range of 6.5-8.1. The change in pH value is less affected by temperature, so it has strong practicality.
2. High stability. TES sodium salt has high thermal stability, and even when conducting relevant experiments in high-temperature environments, it will not affect the buffering effect.
3. Biocompatibility. The pH value of TES sodium salt is relatively close to the neutral value, so it can be compatible with various biological reagents and suitable for various biological experiments.
1. Cell culture: TES sodium salt is suitable as a buffer for cell culture medium, stabilizing the pH value of the medium within the range suitable for cell survival.
TES sodium salt powder needs to be sealed during storage to avoid moisture and isolate air; All equipment and glassware used during the preparation process should be cleaned and disinfected; TES sodium salt solution needs to be prepared and used immediately. It is not recommended to pour the unused solution directly into the sewer. Preventive measures should be taken to avoid contamination.
Each buffer developed has a specific buffer capacity and buffer range. Buffer capacity is the amount of acid or base that can be added before a significant change in pH begins. It can also be defined as the amount of strong acid or strong base that must be added to change the pH value of one liter of solution by one pH unit. After adding acidic or alkaline components, it plays a role in resisting pH changes. Maintain a relatively stable pH value of the solution by neutralizing a small amount of added acid or base.
