Poly(2-hydroxyethyl methacrylate)-graft-polyamine copolymers were developed for column adsorbents for separating lymphocyte subpopulations collected from rat mesenteric lymph nodes. Bead-shaped adsorbents were prepared by coating poly(2-hydroxyethyl methacrylate)-graft-polyamine copolymer on glass beads. Separation features of the column packed with poly(2-hydroxyethyl methacrylate)-graft-polyamine copolymer-coated glass beads were evaluated under various operating conditions. Separation efficacy, AB/AT, was significantly affected by the infusion rate of lymphocyte suspension into the column, increasing with decreasing infusion rate. T cell purity in the column effluent was almost 95% at the infusion rate of 0.1 ml/min. The infusion rate was also found to affect the detachment of adsorbed lymphocytes from the poly(2-hydroxyethyl methacrylate)-graft-polyamine copolymer surface by mechanical pipetting; lymphocytes adsorbed at a low infusion rate were able to be detached quantitatively by suspending the lymphocyte-adsorbed beads with gentle pipetting. The detached lymphocytes thus obtained were confirmed to be enriched in B cells 1.4 times the initial mixture of B and T cells. The addition of albumin in the medium was found to affect the processes of adsorption and recovery of lymphocyte.
