Conventional radioimmunoassays for IgG rheumatoid factors (RF) detect the binding of IgG RF (or their F(ab')2 fragments) to solid-phase human IgG Fc fragments or rabbit IgG. Binding is detected with a radiolabeled antibody that is IgG-specific but is nonreactive with human Fc (i.e., an alpha-Fd reagent) or with rabbit IgG. Anti-Fd reagents are quite laborious to produce. We developed a murine monoclonal alpha-Fd antibody, confirmed its specificity, and compared it with conventional rabbit alpha-Fd in the IgG RF radioimmunoassay. We also adapted the assay to an enzyme-linked assay with both human Fc and rabbit IgG as antigen. We compared the four assay methods with each other and examined their relationship to certain clinical and laboratory features of rheumatoid arthritis.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D001172 Arthritis, Rheumatoid A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated. Rheumatoid Arthritis

D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
