Some Physicochemical and Biological Properties of High Molecular Weight and Globulins in Chicken Sera.

Abstract

The agglutination of latex particles and other particulate bodies by chicken sera has been shown to be due to the presence of certain high molecular weight gamma and B globulins with s rates of 19-22 S and this technique promises to be a simple reliable tool to study some of the properties of these proteins. It has been shown that these proteins are active only in their native state and not following depolymerization. Agglutination is inhibited by the prior addition of other proteins, especially those with a basic charge. This is probably due to the prior coating of the particle by these proteins.
