摘要
A method of detecting antibodies to native deoxyribonucleic acid (n- DNA), anti-nuclear antibodies, antibodies to non-histone containing protein, rheumatoid factors, antibodies to thyroglobulin, and an immunofluorescent assay for such detection is described. The method comprises incubating an insoluble conjugate of methylated bovine serum albumin (mBSA)-native deoxyribonucleic acid (n-DNA) or other substrates with serum from patients with systemic lupus erythematosus (SLE) or other autoimmune diseases for a sufficient length of time, washing the precipitate or flocculate, separating and discarding therefrom the supernatant fluid, adding a fluorescein labeled anti-immunoglobulin antibody to the washed flocculate and incubating the labeled mixture for a sufficient length of time, washing the incubated flocculate and separating therefrom the supernatant fluid, suspending the pellet in a liquid medium to determine the fluorescence of the flocculate, which is proportional to the concentration of antibodies to deoxyribonucleic acid and others in serum specimen. The insoluble conjugate of methylated bovine serum albumin (mBSA)-native deoxyribonucleic acid (n-DNA) retains the double-stranded form of native deoxyribonucleic acid (n-DNA).
