General description
There are five immunoglobulin classes in humans. Out of these, immunoglobulin M (IgM ) is a high molecular weight protein that has five or six subunits. IgM monomers are made of two heavy chains and two light chains connected by a disulfide bond. Human serum shows low concentration of IgM monomers. It has a high carbohydrate content of about 12%. It is the first immunoglobulin produced by neonates.
Specificity
Goat polyclonal anti-Human IgM (μ-chain specific)-Alkaline Phosphatase antibody is specific for human IgM when tested against human IgA, IgG, IgM, Bence Jones kappa, and lambda myeloma proteins. The conjugate shows no reactivity with mouse or rat IgG.
Application
IgM is a glycoprotein with 5 n-linked glycosylation sites on the heavy chain. An ELISA assay was performed to identify glycosylated forms of IgM that bind to lectin. Alkaline phosphatase conjugated goat anti-human IgM was used as the secondary at 1:2000 and developed using p-nitrophenyl substrate (Sigma).
Biochem/physiol Actions
Immunoglobulin M (IgM) acts as an antigen specific part of the B cell antigen receptor on the surface of B lymphocytes that are not stimulated, in its monomeric form. Polymeric IgM molecules also serve as important activators of the classical complement cascade. IgM is essential in agglutination and cytolytic reactions.
Immunoglobulin M (IgM) antibodies appear early in the course of infections. IgM antibodies are responsible for agglutination of red blood cells in mis-matched blood transfusions. The level of IgM may vary with the status of disease or infection. Alkaline Phosphatase is an enzyme that catalyzes the conversion of chromogenic substrates such as p-nitrophenylphosphate (PNPP); chemiluminescent substrates such as CDP-Star® and fluorogenic substrates such as 4-methylumbelliferyl phosphate (4-MUP) into detectable chromophores, light-emitters or fluorescers, respectively.
Other Notes
No cross-reaction with mouse and rat IgG

Costimulatory and coinhibitory receptor-ligand pairs on T cells and APC control the immune response. We have investigated whether selective blockade of CD28-CD80/86 costimulatory interactions, which preserves the coinhibitory CTLA4-CD80/86 interactions and the function of regulatory T (Treg) cells, abrogates the

Our previous study indicated that normal serum contains complement-fixing natural IgM antibodies reacting with a large variety of randomly generated protein carboxy-termini. Here we show that the "carboxy-terminal" IgM (C-IgM) antibodies specifically react with short peptide sequences located immediately at

The immune system is characterized by the preferential migration of lymphocytes through specific tissues (i.e., tissue tropism). Tissue tropism is mediated, in part, by the α(4) integrins expressed by T lymphocytes. The α(4)β(1) integrin mediates migration of memory T lymphocytes

Involvement of low density lipoprotein (LDL) immune complexes (ICs) in atherogenesis has been proposed. Human FcgammaRIIa receptor (CD32) plays a crucial role in the phagocytosis of IgG(2) ICs and a functional point mutation 131His/Arg diminishes IgG(2) binding to the receptor.
