Abstract

The binding affinities of rheumatoid factors interacting with Gm(a), Gm(x), `non a' and `γ4 non a' antigens have been measured by an equilibrium molecular sieving technique using rheumatoid sera of known specificity and pFc' fragments (≡Cγ3 homology region) from IgG molecules of defined subclass and allotype. All the rheumatoid factors studied showed specific binding with the fragments possessing the homologous antigen. The binding affinities of these rheumatoid factors were low, between 104 and 105 litres/mole. In contrast, no binding occurred between rheumatoid factors and fragments lacking the appropriate antigenic determinant.
