title: Application of a new ultra-microculture system. II. Stimulation of human B lymphocytes.
abstract: An ultra-microtechnique for culturing human B-lymphocytes in glass capillary tubes using a volume of 2 microliter is described. The advantage of this ultra-microculture system is that only a small number of lymphocytes and minute amounts of culture medium (or test factors) are required. Optimal culture conditions for the formation of Ig-secreting plaque-forming cells (PFC) after stimulation of mononuclear cells with pokeweed mitogen are given. Furthermore it is shown that immunoglobulin secreted into culture supernatants by purified B cells in the presence of T cell subsets can be measured in a microELISA.
