Definition

ChEBI: Nonidet P-40 is a poly(ether) macromolecule that is polyethylene glycol in which one of the terminal hydroxy groups has been converted to the corresponding p-octylphenyl ether. A nonionic, non-denaturing detergent, it is used for solubilising membrane proteins during isolation of membrane-protein complexes. n ~ 8. It has a role as a detergent. It is an aromatic ether, a poly(ethylene glycol) derivative and a hydroxypolyether. It is functionally related to a 4-octylphenol.
