Purified IgM isolated from human serum. Freund's complete adjuvant is used in the first step of the immunization procedure.
Human IgM, Fc specific.
The reactivity of the antiserum is directed to the Fc subunit of the IgM molecule, which expresses strict (class) specificity. In immunoelectrophoresis and radial in immunodiffusion using various antiserum concentrations against human serum, a single precipitin line has been obtained which shows a reaction of identity with the precipitin lines obtained with the purified IgM used as immunogen. It does not react with IgG, IgG/Fab fragments and IgA or any non-Ig protein in human serum, as tested by immunoelectrophoresis and double radial immunodiffusion. In immunocytochemical and immunohistochemical staining of IgM at the cellular and subcellular level of appropriately treated cell and tissue substrates. to demonstrate circulating IgM antibodies in serodiagnostic microbiology and autoimmune diseases. to identify a specific antigen using a reference antibody of human origin known to be of the IgM isotype in the middle layer of the indirect test procedure. This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labeled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal. Working dilutions are usually between 1:40 and 1:120, depending on the method used. The applications listed have been tested for the unconjugated form of this product. Other forms have not been tested.
