| Immunogen | A synthesized peptide derived from human Human IgG3 IgG is a monomeric immunoglobulin, built of two heavy chains gamma and two light chains. Each molecule has two antigen binding sites. This is the most abundant immunoglobulin and is approximately equally distributed in blood and in tissue liquids, constituting 75% of serum immunoglobulins in humans. There are 4 subclasses: IgG1 (66%), IgG2 (23%), IgG3 (7%) and IgG4 (4%) . |

Product Overview
Clone ACIA-9 is a rabbit monoclonal antibody that recognizes immunoglobulin heavy constant gamma 3 (gene IGHG3) in human samples and is validated for Western blot and immunoprecipitation. The predicted molecular weight is 41.3 kDa, and the supplier reports an observed band at about 55 kDa.
IGHG3 encodes the constant region of the immunoglobulin γ3 heavy chain, which defines IgG3. This subclass has an unusually long hinge region, strongly activates complement and Fcγ receptors, and has a shorter serum half-life than other IgG subclasses.
