Immunoglobulin G - Wikipedia
In a mouse model of autoantibody mediated anemia using IgG isotype switch variants of an anti erythrocytes autoantibody, it was found that mouse IgG2a was superior to IgG1 in activating complement. Moreover, it was found that the IgG2a isotype was able to interact very efficiently with FcgammaR.

What is IgG2a? - Mabtech
What is IgG2a? Immunoglobulin G (IgG) is the most abundant Ig isotype in serum, making up approximately 80% of all serum Immunoglobulins. In mice, the IgG subclasses are defined IgG1, IgG2a/c, IgG2b, and IgG3.
Immunoglobulin G2a - an overview | ScienceDirect Topics
Immunoglobulin G2a (IgG2a) is a subtype of the IgG class of antibodies that is predominantly induced in viral and intracellular bacterial infections, playing a key role in the immune response against such pathogens.
The solution structure of the human IgG2 subclass is distinct from ...
IgG2 possesses three different isoforms termed IgG2A, IgG2A/B, and IgG2B with different hinge disulfide bonds (8 – 10). IgG2A is regarded as the “classical” or “canonical” IgG2 structure with four intact disulfide bonds in the hinge . The IgG2A/B isoform contains one Fab region disulfide-linked to the hinge, and the IgG2B isoform ...
Immunoglobulin G2a - an overview | ScienceDirect Topics
IgGs represent the most abundant antibodies in serum and their production is increased in B cells activated by antigens. In viral infection, IgG2a and to a lesser degree, IgG1 are dominant. IgG2a can efficiently activate the complement cascade and is a mediator of antibody-dependent cytotoxicity by binding to specific Fc receptors on macrophages.
