General description

Alpaca Anti-Rabbit IgG(Fcγ) single domain Antibody is designed to specifically detect Fc region of rabbit IgG. It is a monovalent, single domain, recombinant antibody derived from the variable region of heavy chain of Alpaca pacous. Based on immunoelectrophoresis and/or ELISA, Alpaca Anti-Rabbit IgG(Fcγ) single domain Antibody reacts with the Fc region of rabbit IgG selectively but not with mouse, human, cynomolgus, rat, goat IgG.

Rabbit research antibodies are widely used in life science research. So far, four isotypes have been identified (IgA, IgE, IgG, and IgM) in rabbits. Each isotype has a different heavy chain. Rabbit has only one IgG subclass. 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. 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.
