RHEUMATOID FACTOR AND THE PATHOGENESIS OF RHEUMATOID ARTHRITIS [PDF]

The Journal of Experimental Medicine, 1961
In analogy with the two categories of reactants which are used in the serological tests for the unusual category of macroglobulins called rheumatoid factor, two fluorescent reactants have been prepared for the detection of rheumatoid factor in situ in tissue sections: fluorescent antigen-rabbit antibody (immune) complex, in the present study, and ...

Multiplicity of rheumatoid factor [PDF]

Arthritis & Rheumatism, 1965
AbstractThe reactions between rheumatoid factor and erythrocytes sensitized by antibodies of human, rabbit and guinea pig origin were studied using absorption, elution, dispersion, inhibition and mixed agglutination experiments. The results indicated that there are separate molecules of the rheumatoid factor combining with γ‐globulin of the three ...

Isolation of rheumatoid factors [PDF]

Arthritis & Rheumatism, 1961
AbstractA method for the separation of rheumatoid factors into two serologically distinct macroglobulins is described. Macroglobulins, reacting with cells coated with human as well as with rabbit gamma globulin, were found to be mainly 19.4S, but occasionally such preparations contained minor constituents sedimenting at 22s as well as 27s ...
