The concentration of hepatic fatty acid-binding protein was determined in the livers of rats at various stages of development from foetus to young adult. Fatty acid-binding protein concentrations were determined by quantifying the fluorescence enhancement on the binding of the fluorescent probe 11-(dansylamino)-undecanoic acid. A 20-fold increase in the concentration of the protein was observed between the foetus and adult, and this increase was confirmed by immuno-blotting. No other protein in the 14,000-Mr range was observed in the foetus. Possible alternative fatty acid-binding proteins could not be detected in h.p.l.c.-fractionated foetal cytosol by the fluorescence-enhancement method.

Fatty acid-binding protein from rat liver is shown to bind the fluorescent fatty acid probe dansyl undecanoic acid. Binding is accompanied by a shift in the fluorescence emission maximum from 550 nm to 500 nm and a 60-fold fluorescence enhancement at 500 nm. These spectral properties have allowed the use of this probe to detect and quantify microgram amounts of liver fatty acid-binding protein during purification procedures. In conjunction with h.p.l.c. the method allows the rapid estimation of liver fatty acid-binding protein in biological samples. The validity of the method is demonstrated by measuring the concentration of fatty acid-binding protein in livers from control and hypolipidaemic-drug-treated rats. The dramatic diurnal rhythm previously reported for this protein [Dempsey (1984) Curr. Top. Cell. Regul. 24, 63-86] was not observed with this method.
