Tween 20 is a transparent viscous liquid that is commonly used in Molecular Biology as a potent nonionic detergent, emulsifier and as a blocking agent in immunoassays, such as Western Blotting [1]. Other uses of Tween 20 include expulsion of membrane peripheral proteins and lysis of mammalian cells[1].
Particularly is Western Blotting, Tween 20 is used to decrease the possibility of unspecific binding of proteins (such as immunoassays) onto the nitrocellulose/nylon membrane[2]. This improves visualisation of the protein of interest by reducing the background noise (mere binding of antibody to the menbrane)[2][3]. Other potent blocking agents include nonfat dry milk, bovine serum albumin, casein and possibly nonfat soymilk[2].
