Abstract:
Equine immunoglobulins are recovered from the pass-through fraction of a QAE column loaded with equine serum in an acidic buffer. The recovered antibodies are electrophoretically free of non-immunoglobulin proteins, including transferrin, and are recovered in a higher yield than with known methods. The purified immunoglobulins may be used to treat failure of passive transfer of maternal immunity to foals.
