General description

Goat Anti-Mouse IgM(µ chain) Alpaca Heavy chain only Antibody is designed to specifically detect mouse IgM. It is a monovalent, single domain, recombinant antibody fused to goat IgG Fc. Based on immunoelectrophoresis and/or ELISA, Goat Anti-Mouse IgM(µ chain) Alpaca Heavy chain only Antibody reacts with the µ chain of mouse IgM selectively but not with mouse, rabbit, human, cynomolgus, rat, goat 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. IgM accounts for 5-10% of the immunoglobulin pool and is the predominant antibody in the primary immune response. Unlike IgG, IgM does not contain a hinge region but does contain an additional constant domain. The monomeric form IgM has a molecular weight of 180 KD. It is classically represented as a pentamer of the basic four chain structure held together by a J chain but can also exist in a hexameric form without the J chain and as a monomer on the surface of B-cells.

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.
