TWEEN 20 is widely used in several biochemical applications. It has been used:

As an emulsifying agent for the preparation of stable oil-in-water emulsions[2]
In pre-extraction of membranes to remove peripheral proteins (used at 2% for extraction of membrane-bound proteins)[3]
As a blocking agent for membrane based immunoassays at a typical concentration of 0.05%
For lysing mammalian cells at a concentration of 0.005 to 0.5%
