Anti-ds-DNA-A ELISA

The Anti-ds-DNA-A ELISA is a solid phase enzyme immunoassay with human recombinant double stranded DNA (dsDNA) for the quantitative and qualitative detection of IgA antibodies against dsDNA in human serum. Anti-dsDNA antibodies mainly recognize the phosphate units of DNA, thus these autoantibodies also bind single stranded DNA (ssDNA). To ensure correct quantitation of anti-dsDNA antibodies the antigen used in the kit has been proven to be free of contamination with ssDNA. The Anti-ds-DNA-A ELISA is a tool for the study of systemic lupus erythematosus (SLE).
