[Immunochemical characteristics of the ovine polymeric haptoglobin HpC].
It was found that haptoglobins of camel, cattle, horse, pig, rat, guinea pig and man form upon immunoelectrophoresis precipitation arcs with antibodies against polymeric sheep haptoglobin C, corresponding to alpha 2-globulins. The immunocrossreactivity of haptoglobins of man and various animal species towards antibody to sheep haptoglobin (100, 88.0, 75.2, 72.1, 56.3, 51.0, 41.3 and 28.0% for haptoglobin of sheep, camel, pig, cattle, man, rat, guinea pig and horse, respectively) was determined. The intensity of crossreactions between sheep haptoglobin and the proteins under study towards antibody to haptoglobin C reflects the similarity of their primary structure and, consequently, the immune homology of their molecules. Using quantitative titration, the antigenic valency values for human (6), sheep (5), cattle (4) and horse (3) haptoglobins were determined.
