Mouse IgM ELISA kits
Pick the right ELISA kit for Mouse IgM. Our kits differ in how you develop the signal – this page explains what those differences mean.
What differs between these kits
Which detection system
Available with Streptavidin-ALP or Streptavidin-HRP. You add the streptavidin conjugate as a second incubation after the biotinylated antibody, which amplifies the signal. Alkaline phosphatase (ALP) and horseradish peroxidase (HRP) perform equivalently, so that choice usually comes down to the substrate and reader you already work with.
Supplied without a plate, streptavidin conjugate, enough for 6 plates
About IgM
These Mouse IgM ELISA kits target Ighm (Mus musculus, Gene ID 16019).
Immunoglobulin M (IgM) is the first antibody isotype (also called class) secreted by the adaptive immune system in response to a foreign antigen. Plasma B cells secrete IgM mainly as pentamers, i.e., five IgM molecules joined together by the J chain. Because IgM is formed early in the immune response and is later replaced by IgG, specific antibodies of the IgM class are characteristic of a recent, ongoing, or chronic infection. Therefore, IgM represents the isotype with the lowest affinity for antigens. Due to its structure, with 10 antigen-binding sites per IgM pentamer, it can nevertheless bind surface-bound antigens with very high avidity. Immunoglobulin M constitutes approximately 10% of the total immunoglobulin concentration in serum. Resting mature yet naive, B lymphocytes express monomeric IgM as a transmembrane antigen receptor that functions as part of the B cell receptor (BCR).
