General description

Immunoglobulin M (IgM) is the major component of antibodies. It is the first antibody to be secreted during a primary antibody response, which is expressed in the human fetus. IgM is produced by B1 cells, which is found in blood.

Specificity

The antibody preparation is specific for human IgM when tested against purified human IgA, IgG, Bence Jones Kappa and Bence Jones Lambda light chains

Biochem/physiol Actions

IgM antibodies are present as pentamers in the serum and are produced in response to antigens.
Immunoglobulin M (IgM) pentamer activates the classical pathway of complement activation and lysis of red blood cells. Monoclonal IgM antibodies provides protection against systemic infection and autoimmune diseases. It does not cross human placenta. IgM regulates B cell development.

Physical form

Supplied as a liquid containing 15 mM sodium azide as a preservative.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.

Humans evolved by losing the capacity to synthesize the glycan Galα1-3Galβ1-(3)4GlcNAc-R (α-Gal), which resulted in the development of a protective response mediated by anti-α-Gal IgM/IgG/IgA antibodies against pathogens containing this modification on membrane proteins. As an evolutionary trade-off, humans can develop
