IgG anti-IgA antibodies were measured by an enzyme-linked immunosorbent assay using one IgA1 and one IgA2 (m1) myeloma and a pooled IgA protein preparation as antigens. Class-specific anti-IgA antibodies occurred in 0.8% of non-IgA-deficient sera and 24.3% of IgA-deficient sera. Antibodies reacting with IgA1 only occurred in 2.6% of non-IgA-deficient sera and 6.7% of IgA-deficient sera. Antibodies reacting with IgA2 only occurred in 0.6% of non-IgA-deficient sera and 2.7% of IgA-deficient sera… CONTINUE READING
