The covalent coupling of proteins to periodate-oxidized sephadex: a new approach to immunoadsorbent preparation.

Proteins were covalently coupled in good yield to periodate-oxidized Sephadex. The reaction was studied in detail with respect to Sephadex type, sodium m-periodate concentration, protein (albumin or immunoglobulin) concentration, time course, temperature dependence, and pH optimum. The complexes were stable and were used successfully for the immunoadsorption of sheep anti-rabbit immunoglobulin antibodies.
