Detergents: Triton X-100, Tween-20, and More

Oct 07, 2020 · The temperature at which the detergent solution separates into two phases, the cloud point, is affected by glycerol or salts in the buffer (e.g., Triton X-114 has a cloud point of 23°C, but in the presence of 20% glycerol, the cloud point declines to 4°C). This is very important since the stability of a protein is affected by high temperatures.
