Reactivity
Human
(tested or 100% immunogen sequence identity)
Conjugations
Unconjugated
Immunogen
Highly purified polyclonal IgM isolated from human serum. Freund's complete adjuvant is used in the first step of the immunization procedure.
Specificity
Human immunoglobulin IgM, Fc specific.
Usage
The reactivity of the antiserum is directed to the Fc subunit of the IgM molecule which expresses strict isotypic (class) specificity. It does not react with any non-Ig protein in human serum, as tested by immunoelectrophoresis and double radial immunodiffusion. This antiserum is intended to detect and identify IgM in serum or other body fluids using the immunofixation technique. Like immunoelectrophoresis immunofixation is essentially a two step technique. Proteins in a complex mixture are separated by electrophoresis in a gel carrier, followed by immunoprecipitation in situ with the antiserum. Non-precipitated proteins are removed by washing and the precipitated complex is revealed with a protein stain which allows its exact localization. Immunofixation may be the method of choice whenever a high level of sensitivity is required to identify a minor protein component against a high background of other proteins. It enables the detection and identification of more than one paraproteins in serum or of free light chain. The detection limit is approximately 0.5 to 1 mg/ml in the presence of normal levels of immunoglobulins. This product is not pre-diluted. The optimum working dilution of each product should be established by titration before being used.
