Isotype IgG4
Characteristics This protein carries no "tag". The protein has a calculated MW of 25.8 kDa. As a result of glycosylation, the protein migrates as 33-35 kDa under reducing (R) condition, and 50-55 kDa under non-reducing (NR) condition (SDS-PAGE).
Purity >95 % as determined by SDS-PAGE.
Sterility 0.22 μm filtered
Endotoxin Level Less than 1.0 EU per μg by the LAL method.
Alternative Name IgG4
Background 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).
Molecular Weight 25.8 kDa
UniProt P01861
Research Area Secondary Antibodies
Application Notes Optimal working dilution should be determined by the investigator.
