IgM Isotype Control from murine myeloma，0.1MG，M5909-.1MG，Sigma

General description

IgM is a glycoprotein antibody that regulates humoral immune responses. Mouse IgM is involved in modulating B cell memory . This antibody isotype has also been implicated in the development of autoimmune responses associated with the pathogenesis of type 1 diabetes in mice . IgM isotype control antibody is specific for anti-mouse whole serum and anti-mouse IgM. The product does not react with antisera to mouse IgA, IgG1, IgG2a, IgG2b, and IgG3.
Isotype controls are non-reactive immunoglobulins of the same isotype as the primary antibody being used in an application. It is recommended that a non-reactive immunoglobulin of the same isotype and concentration be included as a negative control for each monoclonal antibody reagent used in flow cytometry or other immunoassays.
The purified IgM Isotype Control clone MOPC 104E preparation is non-reactive with antisera to mouse IgA, IgG1, IgG2a, IgG2b, and IgG3. When evaluated in flow cytometry, the IgM Isotype Control did not stain human peripheral blood lymphocytes (PBLs). A FITC Goat anti-Mouse IgM (μ-chain specific), Affinity Isolated Antibody (Product No. F 9259) along with 1 μg of the product was incubated with human PBLs and then evaluated by flow cytometry.

Application

IgM Isotype Control from murine myeloma has been used:

• in chromatin immunoprecipitation (ChIP) assay
• LABScreen assays
• immunofluorescent staining

Biochem/physiol Actions

The specificity of staining by monoclonal antibodies to mouse CD antigens should be verified by establishing the non-specific reagent binding to the target cell population. It is recommended that a concentration and isotype matched mouse myeloma immunoglobulin be included as a negative control for each monoclonal antibody reagent used in the immunoassay procedure.
Sigma Mouse Isotype Controls are supplied to match the concentration of Sigma purified and/or conjugated monoclonal antibodies to CD antigens. DUAL-TAG controls contain 100 μg of each conjugate.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide
