Abstract
THE clarification of agar has always presented technical difficulties. The problem has become even more acute with the application of agar gels as a supporting medium for the interaction of antigen–antibody systems. A clear, transparent gel is essential for reading and photographing the lines, often fine and faint, formed by the antigen–antibody precipitates. That the classical microbiological methods of clarification, for example, filtration through sand and paper pulp, egg albumin coagulation, are insufficient is obvious from the elaborate, laborious methods devised in attempts to produce clear agar1,2.
