title: Identification of haptoglobin in chicken serum and specificity of the chicken haptoglobin-hemoglobin complex formation.
abstract: 1. The presence of haptoglobin in chicken serum has been demonstrated by three different techniques: gel filtration, cellulose acetate electrophoresis and fluorescence quenching. 2. Chicken haptoglobin shows a narrow species specificity; it binds only avian and reptilian but not mammalian hemoglobins. 3. Haptoglobin seems to have been subjected to profound changes during the course of evolution.
