Potential methodological errors in the application of equilibrium dialysis to the determination of "free" and "bound" plasma tryptophan.
The application of equilibrium dialysis to the determination of the "free", i.e. non-albumin bound fraction of human plasma or serum tryptophan has been re-examined. A potentially serious error in the application of this method is outlined and the necessary correction and some precautionary measures are discussed.
