Description

General description

Alpaca Anti-Human IgG(Fcγ) single domain Antibody is designed to specifically detect human IgG Fcγ fragment. 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-Human IgG(Fcγ) single domain Antibody react with the Fc fragment of human IgG heavy chain but not with the Fab portion of human IgG.
In mammals, antibodies are classified into five main classes or isotypes – IgA, IgD, IgE, IgG and IgM. They are classed according to the heavy chain they contain – alpha, delta, epsilon, gamma or mu respectively. IgG is the most abundant antibody in normal human serum, accounting for 70-85% of the total immunoglobulin pool. Human IgG consists of four human subclasses (IgG1, IgG2, IgG3 and IgG4), and each contains a different heavy chain. 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(kappa or lambda). 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.
