a new approach to immunochemical analysis of complex mixtures of proteins has been devised through development of a system for ( 1 ) sequentially absorbing , desorbing , and cascading antibodies in a profile indicative of both the quantity and electrophoretic characteristics of the antigen , and ( 2 ) for carrying out multiple tests of antigenic determinants at sub-picomole levels regardless of the solubility or precipitin forming characteristics of the immunoreactive protein .
