ANTI-HUMAN IGM (MU CHAIN SPECIFIC) &

Description_x000D_ General description_x000D_ 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._x000D_ Specificity_x000D_ 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._x000D_ Application_x000D_ 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)._x000D_ Physical form_x000D_ Solution in 0.05 M Tris, pH 8.0, containing 1% bovine serum albumin, 1 mM MgCl2 and 15 mM sodium azide_x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Legal Information_x000D_ CDP-Star is a registered trademark of Tropix, Inc._x000D_ Biochem/physiol Actions_x000D_ 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._x000D_ 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._x000D_ Other Notes_x000D_ No cross-reaction with mouse and rat IgG
