Abcam’s anti-Rheumatoid Factor IgM ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative determination of autoantibodies to Rheumatoid Factor IgM in Human serum or plasma.
The quantitative immunoenzymatic determination of IgM rheumatoid factors is based on the ELISA (Enzyme-linked Immunosorbent Assay) technique. Microtiter strips are precoated with Fc fragments of Human immunoglobulin G to bind corresponding antibodies of the specimen. After washing the wells to remove all unbound sample material horseradish peroxidase (HRP) labelled anti-Human IgM conjugate is added. This conjugate binds to the captured rheumatoid factors. The immune complex formed by the bound conjugate is visualized by adding Tetramethylbenzidine (TMB) substrate which gives a blue reaction product. The intensity of this product is proportional to the amount of IgM rheumatoid factors in the specimen. Sulphuric acid is added to stop the reaction. This produces a yellow endpoint colour. Absorbance at 450 nm is read using an ELISA microwell plate reader.
