Dry polyacrylamide batch method for determining the binding of various compounds by plasma proteins.
A new modification of the gel diffusion method has been developed using dry polyacrylamide gel. The theoretical background is explained and the mathematical formulas are presented. The properties of the gel are studied, concerning the absorbing capacities and changes in ion equilibria. As a model compound the freely diffusible calcium is assayed and the result obtained (52.4 +/- 2.9%) agrees well with the results from previous methods by other authors. The accuracy of the method is discussed and the theoretical explanation to the sensitivity in determinations is calculated.
