The use of protein beads as immunoadsorbent for the column fractionation of lymphocytes

Beads of calf serum proteins (CSB) with antigen-antibody complexes or antigen by activation with glutaraldehyde were used as immunoadsorbents for the fractionation of mouse lymphocytes. T-lymphocytes could be separated by this method with high purity. The precursors of antibody-forming cells were completely eliminated from spleen and bone marrow cell suspensions. The unspecific binding of lymphocytes to CBS or Sepharose was similar and not selective for T or B lymphocytes.
