Description

Packaging

1, 5 mg in glass bottle

10 mg in serum bottle

Physical form

Solution in 0.05 M Tris-HCl, 0.2 M sodium chloride, pH 8.0, containing 15 mM sodium azide.

Application

Purified human IgM may be used as a reference antigen, standard, blocking agent, or coating protein in a variety of immunoassays including ELISA, dot immunobinding, Western immunoblotting, immunodiffusion, and immunoelectrophoresis. Other applications include starting materials for the preparation of immunogens and solid phase immunoadsorbents. IgM from human serum was used as standard in ELISA (100 μg/ml) and dot blot assay. Antibody concentration range of 200 μg/ml to 1 mg/ml was used in IgM binding assays.

General description

IgM antibodies are present as pentamers in the serum and are produced in response to antigens
IgM from human serum is purified from normal human serum by precipitation and gel filtration techniques. The immunoglobulin is determined to be atleast 95% pure by HPLC procedures.
