Anti-dsDNA IgG ELISA Kit

Catalog No. ABIN1326829

Product Details

Target: Anti-dsDNA IgG

Reactivity: Human

Detection Method: Colorimetric

Method Type: Competition ELISA

Application: ELISA

Purpose: Diluted patient serum is added to wells coated with purified dsDNA antigen. Specific antibody, if present, binds to the antigen. All unbound materials are washed away and the enzyme conjugate is added to bind to the antibody-antigen complex, if present. Excess enzyme conjugate is washed off and substrate is added. The plate is incubated to allow the hydrolysis of the substrate by the enzyme. The intensity of the color generated is proportional to the amount of specific antibody in the sample.

Sample Type: Serum

Analytical Method: Qualitative

Target: Anti-dsDNA IgG

Target Type: Antibody

Background: Anti-dsDNA is present in 50 % to 70% of patients with systemic lupus erythematosus (SLE). Circulating DNAanti-DNA immune complexes are considered to play a part in the pathogenesis of SLE. The presence of anti-dsDNA is one of the diagnostic criteria for SLE. IgG antibodies to dsDNA are considered clinically most useful for the diagnosis and management of SLE. Antibodies to single stranded DNA (ssDNA) and IgM antibodies to DNA are found in a number of other connective diseases, liver diseases, as well as in some normal iniduals. ELISA is the method of choice for the screening of anti-dsDNA in-patients with suspected SLE.
