Unlike additional immunoglobulin G (IgG) subclasses, IgG4 antibodies in plasma have already been reported to become monovalent functionally. led to disappearance SB-408124 from the bispecific activity. By size exclusion chromatography we excluded the chance that bispecific activity was due to aggregation of IgG4 antibodies. These outcomes indicate that circulating (polyclonal) IgG4 antibodies possess two different… Continue reading Unlike additional immunoglobulin G (IgG) subclasses, IgG4 antibodies in plasma have
