产品说明
一般描述
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.
特异性
This product was prepared from monospecific antiserum by immunoaffinity chromatography using Human IgM coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities. Assay by immunoelectrophoresis resulted in a single precipitin arc against Anti-Rabbit Serum, Human IgM and Human Serum. Specificity was confirmed by ELISA at less than 1% cross reactivity against other Human heavy or light chain isotypes.
免疫原
Human IgM Fc5μ fragment
生化/生理作用
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.
