Abstract
Cell lines BTSN4 and BTSN5 were produced by the Epstein-Barr Virus (EBV) transformation of B-lymphocytes from the same human donor. Both secrete an anti-D monoclonal of the IgG1 subclass but these antibodies display vastly different effector activities. Specifically, anti-D from BTSN4 has a far greater activity in both monocyte- and lymphocyte-mediated ADCC reactions and causes a higher percentage of rosettes to be formed with monocyte-like U937 cells. This variation in functional activity is shown to coincide with changes in the structure of the sugar chains attached to the asparagine-297 site on the immunoglobulin heavy chain.Entities:
