Abstract of the Disclosure A process and apparatus for the recovery of immunoglobulins of high purity and potency from milk, in which process milk in passed through a re-usable immunoadsorbent column comprising an insoluble carrier material to which is bound a low-affinity monoclonal antibody specific to one or more milk immunoglobulins but not specific to any other common constituent of milk, the antibody bind immunoglobulin molecules, and following removal of the residue of the milk the immunoglobulin molecules are-released by eluting the immunoadsorbent. The apparatus preferably comprises two or more immunoadsorbent columns in parallel, with means for eluting each column and means for flushing each column before and after elution. (Fig 2.) |
