Abstract
The fluorescence enhancement effect in rare earth-protein-sodium dodecyl benzenesulfonate (SDBS) system has been studied. Tb3+-SDBS-protein system showed a very weak fluorescence, while addition of Gd3+or ethanol to this system significantly enhanced the fluorescence, especially in collagencontainining system. This new method made it possible to determine proteins of ng/ml level.
