Native Protein IgG2There are four IgG subclasses (IgG1, 2, 3 and 4) in humans, named in order of their abundance in serum (IgG1 being the most abundant). Human IgG2 subclass has been identified to exist as an ensemble of distinct isoforms, designated IgG2-A, IgG2-B, and IgG2-A/B, which differ by the disulfide connectivity at the hinge region. IgG2, the second largest part of IgG isotypes in humans, comprises 20-25 % of the main subclass and is the prevalent immune response against carbohydrate-/polysaccharid antigens. The antibody is a mouse monoclonal antibody raised against IgG2.
