1 The enhancement of the fluorescence quantum yield of 1,8-anilinonaphthalenesulfonic acid (ANS) upon binding to intestinal fatty acid protein (I-FABP) was exploited to devise an assay for free I-FABP. Fatty Acids fatty acid binding protein 2 Rattus norvegicus
2 The enhancement of the fluorescence quantum yield of 1,8-anilinonaphthalenesulfonic acid (ANS) upon binding to intestinal fatty acid protein (I-FABP) was exploited to devise an assay for free I-FABP. Fatty Acids fatty acid binding protein 2 Rattus norvegicus
3 With this assay, we monitored the competition for free I-FABP between ANS and fatty acids and thereby extracted values for the dissociation constants (K(FA)) of fatty acids for I-FABP. Fatty Acids fatty acid binding protein 2 Rattus norvegicus
4 With this assay, we monitored the competition for free I-FABP between ANS and fatty acids and thereby extracted values for the dissociation constants (K(FA)) of fatty acids for I-FABP. Fatty Acids fatty acid binding protein 2 Rattus norvegicus
5 We compare the values of delta H degrees, delta S degrees, and delta C(p)degrees for fatty acid binding we have obtained in this work with those we found in earlier work with ANS binding to I-FABP [Kirk et al. Fatty Acids fatty acid binding protein 2 Rattus norvegicus
6 Our interpretation of the origin of the thermodynamic changes for ANS binding in our earlier work is here substantiated and extended to include an evaluation in physical terms of the interaction of I-FABP with fatty acids. Fatty Acids fatty acid binding protein 2 Rattus norvegicus
