Human rheumatoid factor IgM ELISA kit is designed for detecting in-vitro quantitative amounts of IgM antibodies to anti-rheumatoid factor IgM (RF, RF-IgM, rheumatoid factor IgM) in human serum or plasma. This assay has a minimum analytical sensitivity limit of 1.0 IU/ml.
Rheumatoid factor (RF) was first discovered in rheumatoid arthritis, it is mainly found as the isotype IgM but it can also be in IgA, IgD, IgE and IgG form. RF is found as an antibody directed against the Fc portion of IgG, however, there are many different RFs proteins which are able to attach to specific sections of the IgG-Fc molecule. The following rheumatoid factor-IgM ELISA kit is intended for analysing many different types of diagnostic applications. Rheumatoid factors are useful diagnostic markers for individuals that are suspect for rheumatoid arthritis or any other related autoimmune conditions.
