Description
General description
Alpaca Anti-Mouse kappa Biotin single domain Antibody is designed to specifically detect mouse IgG kappa chain. It is a monoclonal, single domain, recombinant antibody to mouse IgG kappa chain coupled to Biotin. Based on immunoelectrophoresis and/or ELISA, Alpaca Anti-Mouse kappa Biotin single domain Antibody reacts with the mouse IgG kappa chain selectively but not with the mouse IgG lambda chain or heavy chain of mouse IgG.
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(kappa or lambda), 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(<15KDa) 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.
