title: Antiglobulins in normal human sera which react with baboon Ig G.
abstract: Antiglobulins of the Ig M class which react with the Ig G of baboons have been discovered in approximately half the number of normal human sera investigated by the technique of hemagglutination of red blood cells coated with baboon immune serum. The frequency of these antiglobulins is significantly higher among patients suffering from seropositive rheumatoid arthritis but there is no correlation with the presence of Milgröm-type antiglobulins. The inhibition of several sera containing these antiglobulins by the sera of baboon of different species is also reported.
