- Scientific DescriptionCharacteristics: This protein carries no "tag". The protein has a calculated MW of 25.8 kDa. As a result of glycosylation, the protein migrates as 30-32 kDa under reducing (R) condition, and 28-30 kDa and 55-60 kDa under non-reducing (NR) condition (SDS-PAGE). Description: Immunoglobulin G4 (IgG4) is a member of many immunoglobulin G developed and secreted by effective B cells. In wake of cutting by pepsin, IgG is divided into two F(ab)s with one antigen binding site and a high conserved Fc segment. The Fc segment bears a highly conserved N-glycosylation site. Ig gamma-4 chain Fc region contains two constant regions of IgG4 H chain (CH2, CH3).
