The method of multilayer gel plates for the analytical immunochemical techniques.

A new analytical immunochemical method using gel film copies obtained by means of multilayer gel plates is described. The method is suitable for any variant of immunochemical gel technique. Perfect identity of the copies as well as some advantages are exemplified. In comparison with the already known monolayer gel plate method, the multilayer plate is more advantageous for the study of the dynamics of the antigen-antibody reaction, for the discovery of the nature of some unknown biological products available in very low quantities and for the discovery of the nature of some unknown biological products available in very low quantities and for the economy of certain costly reagents. Moreover, its high reproductibility recommends it as a reference method for the control of quality, especially of the precision and accuracy of the monolayer immunofiltration techniques.
