A New Technique for Determination of Immobilizing Antibodies againstiE. coli/iUsing Capillary Tubes

摘要

A new technique for determining immobilizing Escherichia coli antibodies is described. Capillary glass tubes were filled with semisolid, lactose-containing agar, supplemented with the antiserum to be tested. The highest dilution of antiserum still immobilizing the bacteria was registered.
