On the unification of the Wassermann reaction. Breen and Solun (Vest. Micr., VI, Vol. 3)

Working with several series of "Moscow" antigens from the Central Bacteriological Institute, Breen and Solun found that these antigens, with their strongly pronounced anti-complementary properties, can give false delays, on the one hand, because not all tested sera neutralize this anti-complementary property. not all tested sera neutralize this anticomplement property of the antigens and, on the other hand, can also produce frequent negative results because the main experience when the tested serum neutralizes the anticomplement properties of the antigen occurs in an excess of complement.
