Chemical Properties

It is soluble in water


Tween 20 blocking buffer solution is used as a washing agent in immunoassays, such as Western blots and ELISAs. It helps to prevent non-specific antibody binding. The buffer is used for washes between each immunoreactions, to remove unbound immunologicals, and eventually for incubation solutions of immunoreagents (labeled antibodies) to reduce unspecific background.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
