Alkylphosphine oxides ( APO ) are a family of non ionic
detergents with a wide range of versatile uses. The detergents
are pure crystalline solids, soluble in water and the solutions
are stable over long periods. Ideally the alkyl phosphine
detergents have low CMC values, are UV transparent and P31 NMR
detectable. Alkyl phosphine oxide detergents have been used for
purification of high purity DNA without the need to use resins
or phenol/chloroform. APO 8 has been used in the two phase
separation and purification of proteins.
