Polystyrene microspheres were coated with polyamine graft copolymer and mixed with rat lymphocyte suspension.In the mixture of T and B cells, the microspheres formed large aggregates, while they were fairly well dispersed in the T cell suspension. This result was understood to be the result of preferential adsorption of B cells to the microspheres, indicating it would be possible to deliver drugs to B cells alone with these copolymer-coated microspheres.
