title: Immunochemical studies on beta-lactoglobulins. precipitin reactions of sow's and mare's mammary secretions against anti - bovine beta - lactoglobulin antiserum.
abstract: By double diffusion in agarose gel, in well defined experimental conditions, cross reactions were observed between porcine beta-lactoglobulins and anti-bovine beta-lactoglobulin antisera. The immunological reactivity between these beta-lactoglobulins from a monogastric and the ruminant anti beta-lactoglobulin antiserum thus implies a certain degree of similarity between the monomeric beta-lactoglobulins examined and the dimeric of the ruminants. With the same antisera it also proved possible to demonstrate the presence of beta-lactoglobulins in the mammary secretions of another monogastric, namely, the mare. Identity reactions observed between sow's and mare's beta-lactoglobulins seem to indicate a close similarity in their structures.
