AROTEC - Model ATF01 - Rheumatoid Factor Antigen - Brochure

AROTEC`s Rheumatoid Factor (RF) antigen (Human IgG Fc fragment) is purified from human plasma and can be used to detect rheumatoid factors in patient sera. Rheumatoid factors are a subcategory of immunoglobulins that specifically bind to the Fc regions of IgG. Elevated concentrations of rheumatoid factors are often correlated with a more severe course of the disease. IgM RF may precede the onset of RA by several years. In established RA, high titer serum IgM RF indicate poor prognosis.
