title: A simple method for determination of the concentration of anti-dextran IgG in antiserum by means of affinity electrophoresis.
abstract: A simple technique for determination of the concentration of anti-dextran IgG in antiserum using affinity electrophoresis is described. In the presence of an excess of intermediary molecular size dextran in the polyacrylamide gel, polyclonal anti-dextran IgG migrated in a single sharp band, separated from the nonspecific IgG fraction and other serum protein fractions. With this technique, 1-10 micrograms anti-dextran IgG in antisera can be determined within 3 h. We call the procedure ligand saturating affinity electrophoresis.
