General description

Immunoglobulin M (IgM) is a member of immunoglobulin family. It exists as a pentamer in the serum and has a high molecular weight. Monomeric IgM has a molecular weight of 190 kDa. The pentameric IgM is characterized with ten μ heavy chains, ten light chains and a single J-chain which is linked by disulphide bonds. The μ chain consists of five domains- VH, Cμ1, Cμ2, Cμ3 and Cμ4. Limited digestion using papain cleaves the antibody into three fragments, two of which are identical and contain the antigen-binding activity. They are known as fragment antigen binding (Fab) fragments. The third fragment does not possess antigen-binding activity and is known as fragment crystallizable (Fc). It interacts with cells and effector molecules. The heavy chains of IgM contain an extra C domain that replaces the hinge region. IgM is the first antibody to be produced during an immune response and is the major isotype secreted in T-cell independent immune responses.

The antibody CH2 reacts with Fc fragment of human IgM.


Purified human IgM


The reagent is designed for Flow Cytometry analysis. Suggested working dilution for Flow Cytometry is 1 μg/mL of sample. Indicated dilution is recommended starting point for use of this product. Working concentrations should be determined by the investigator.
