Antibodies in man and other species are associated with a group of proteins closely related structurally and functionally and collectively known as the immune globulins. Most of them fall in the 7S gamma globulin fraction with a molecular weight of 160,000. Some are thought to belong to the γ1A (β2A) globulins of similar size, and an ever increasing number of antibodies and biologically active substances such as the rheumatoid factor and properdin are found in the 19S gamma globulin (γ1m, β2m) fraction which has a molecular weight of about a million and is richer in carbohydrates. In addition to their
