title: Antibodies against protein antigenic sites that are identical in the homologous protein of the immunized animal. Autoreactivity in rabbits of antibodies to sperm-whale myoglobin.
abstract: Sequence comparisons between the antigenic sites of sperm-whale myoglobin and the corresponding regions in rabbit myoglobin indicate that rabbits make antibodies to regions of the sperm-whale myoglobin molecule which are identical to the corresponding regions in rabbit myoglobin. Rabbit myoglobin did not precipitate with antisera to sperm-whale myoglobin. However, it exhibited an extensive cross-reaction as demonstrated by its ability to inhibit the precipitin reaction of sperm-whale myoglobin, and on an immunoadsorbent, bound a large amount of antibodies to sperm-whale myoglobin.
