[Micromethod of determining the complement-binding properties of commercial series of the foot-and-mouth disease virus].

Investigations were carried out to establish the possibility of using a micromethod of the complement-fixation test to determine the complement-fixing properties of productional series of the foot-and-mouth disease virus. It was found that the micromethod referred to is an economically profitable and practically simple one. It is readily applicable requiring no particular apparatuses and equipment, is specific, and can successfully be used instead of the routinely employed CFT method. The micromethod suggested is economical, requiring minimal amounts (0.025 cu.c7) of the components taking part.
