Principle of Assay
Human ds DNA IgG ELISA Kit (A303133) employs an enzyme immunoassay for the qualitative detection of human ds DNA IgG in serum, plasma, tissue homogenates, and other biological fluids. The 96-well microtiter plate is coated with capture antibodies or antigens specific for ds DNA IgG. Samples are added and incubated, followed by washing and addition of enzyme-conjugated detection molecules. TMB substrate is added to produce a blue-coloured product that turns yellow after acidic stop solution. The presence or absence of yellow color indicates the presence or absence of ds DNA IgG in the sample.
