General description

Goat Anti-Mouse IgG2a(Fcγ) Alpaca Heavy chain only Antibody is designed to specifically detect mouse IgG2a Fcγ fragment. It is a monovalent, single domain, recombinant antibody fused to goat IgG Fc. Based on immunoelectrophoresis and/or ELISA, Goat Anti-Mouse IgG2a(Fcγ) Alpaca Heavy chain only Antibody reacts with the Fc fragment of mouse IgG2a selectively but not with other mouse IgG subclasses, mouse IgM, or the Fab portion of mouse immunoglobulins.

Most monoclonal antibodies are generated in mouse. There are five antibody isotypes (IgA, IgD, IgE, IgG, and IgM) from mouse. Each isotype has a different heavy chain. Mouse IgG constitutes 75% of serum immunoglobulins, and IgG is the predominant form of first antibody produced from mouse. Mouse IgG consists of five subclasses-IgG1, IgG2a, IgG2b, IgG2c(inbred mouse strains with the Igh1-b allele have IgG2c isotype instead of IgG2a), IgG3. They are highly homologous and differ mainly in the hinge region. The whole IgG molecule possesses both the Fc region and the Fab region, which possessing the epitope-recognition site. The IgG contains two heavy and light chains, and the heavy chain is about 50 KD and the light chain is about 25 KD. The common IgG is monomeric with a molecular weight of approximately 150 kD.

VHH are single-domain antibodies derived from the variable regions of heavy chain of Camelidae immunoglobulin. The size of VHH is extremely small(less than15KDa) compared to other forms of antibody fragment, which significantly increase the permeability of VHH. Thus VHH is considered of great value for research, diagnostics and therapeutics.
