Description

Mouse Isotype Control

Description: The mouse IgM is useful as an isotype control immunoglobulin. The immunoglobulin was generated by immunization with lipopolysaccharide (LPS). The immunoglobulin is reactive with LPS. Applications Reported: This mouse IgM isotype control has been reported for use in immunocytochemistry, immunohistochemistry, and flow cytometric analysis. Applications Tested: Mouse IgM Isotype Control Purified has been tested by flow cytometric analysis. Use at the same concentration as the experimental antibody. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm post-manufacturing filtered.

Mouse IgM is an immunoglobulin M antibody that is produced by B cells in response to an antigen. It is the first antibody produced during an immune response and is the largest immunoglobulin in the serum. Mouse IgM is composed of five heavy chains and five light chains, and it is involved in complement activation and agglutination of antigens. It plays a crucial role in the innate immune response and is important for neutralizing pathogens before the adaptive immune response is fully activated. Mouse IgM is widely used in research and diagnostic applications, including ELISA, Western blotting, and immunohistochemistry.

Frequently Asked Questions (FAQs)

Is an isotype control a must for flow cytometry analysis?

No. Many users are using unstained cells in combination with FMO controls to identify their positive populations.

What if I can't find the right isotype control for flow cytomtery?

The flow cytometry field is moving away from using isotype controls as they are not necessarily the most appropriate way to control for non-specific binding. Instead, they are using unstained cells to define the negative population, single stained controls to set compensation, and flow minus one (FMO) controls to set regions and gates.
