[Isolation of antilymphocytic antibodies with the aid of cellular immunosorbents].

The authors suggest a method of obtaining purified antilymphocytic antibodies by mean of a specific immunosorbent of human or mouse lymphocytes fixated with glutharic aldehyde Such immunosorbents subjected to special treatment could be used repeatedly; their sorptive capacity was retained in such case. Only from 5 to 12% of the activity could be obtained from immunosorbents sorbed from the serum with 77--93% activity. In comparison with the initial serum, purification was from 6- to 15-fold. Thus, the suggested method provided considerable purification of the antilymphocytic preparations and permitted to obtain highly active antilymphocytic antibodies.
