[Preparation of antilymphocytic globulin by means of repeatedly-used immunoadsorbents (author's tranl)]
A method is described for the purification of horse anti-human lymphocyte serum, whereby absorption of haemagglutinating antibodies was performed with human RBC ghosts. These ghosts were repeatedly used after desorption. Desorption was carried out in glycine-HCl buffer solution pH = 3,0. The advantages of this method consist of a reduction in the amount of RBC needed for absorption and the relatively low loss of lymphocytotoxic antibodies. The final product is effective in an in vitro test system and complies with the requirements for human use.
