Synthesis and secretion of IgE by an established human myeloma cell line

PMCID: PMC1713130  PMID: 5158272

Abstract

The rate of IgE production in vitro and the cell population proliferation rate by the established human myeloma line 266 Bl have been studied quantitatively under various tissue culture conditions. The rate of extracellular IgE accumulation depended on the type of medium used, the cell density and the period of time elapsed after explantation. The maximum production rate of 8·1 × 10−12 g IgE/cell/48 hr was noticed at cell densities <106/30 ml and with the presence of feeder human skin fibroblasts or glia-like cells or with the use of conditioned media harvested from such cells. The rate of cell proliferation and secretion of IgE to the medium ran parallel suggesting that the IgE production is highest when cells are in the best physiological condition. During more than one year the rate of synthesis of IgE remained stable. This functionally stable human myeloma line is suitable for further studies on immunoglobulin biosynthesis at the cellular and subcellular level under the tissue culture conditions found optimal in this study.
