The association of acrylamide with proteins. The interpretation of fluorescence quenching experiments.
The association properties of acrylamide with a number of proteins in aqueous solution have been investigated by a fluorescence-quenching method previously used in micelles and lipid bilayers (Blatt, E., Chatelier, R.C. and Sawyer, W.H. (1984) Chem. Phys. Lett. 108, 397-400). At pH 7.0, acrylamide partitions between the bulk aqueous phase and the proteins, human serum albumin, monellin and ovalbumin. Comparison with an earlier method of analysis (Sikaris, K.A., Thulborn, K.A. and Sawyer, W.H. (1981) Chem. Phys. Lipids 29, 23-36) confirms the data quantitatively. For human serum albumin at pH 2.2, acrylamide associates according to both partition and binding processes. Equilibrium dialysis experiments performed for the latter system verify that acrylamide associates with proteins.
