RUBELLA COMPLEMENT FIXATION TEST.

Complement-fixing antigens specific for rubella were made in tissue cultures of RK-13 rabbit kidney cells and primary cultures of kidney from the African green monkey. The antigens were prepared with the infected cell monolayer diluted to 30 percent with supernatant fluid and frozen and thawed three times. Complement-fixing antibody appeared in patients with rubella soon after the termination of rash and persisted for at least 8 months. In 8 out of 12 individuals who had the disease 10 to 20 years before they were tested, no complement-fixing antibody was found, but neutralizing antibody was present.

RUBELLA VIRUS: NEUTRALIZING ANTIBODY IN COMMERCIAL GAMMA GLOBULIN.

In 19 lots of standard commercial gamma globulin from humans, the titers of antibody neutralizing rubella virus varied from, 256 to 2048. The titers could not be correlated with geographic location of the donors, method of extraction, or tissue source. Samples of gamma globulin from rubella convalescents had titers of 4096. These titers were approximately 20 times higher than those in serum specimens from patients ill with natural or experimental infection. Serum antibody appears to persist for a number of years at nearly the original titers.
