Target Details for dsDNA

Target: dsDNA (Double-Stranded DNA (dsDNA))

Alternative Name: dsDNA

Target Type: Nucleotide

Background: Optional[Gene Symbols]: The Double Stranded DNA (dsDNA) Human IgG ELISA Kit employs an indirect ELISA method. In this kit, standard 96-well plates (12 strips with 8 wells/strip) are coated with a pathogen antigen, which combines with the corresponding antibody present in a sample and Positive Control, which is used as a calibration curve for interpretation purposes. When a biotinylated secondary anti-human IgG antibody is added, a complex forms between biotinylated secondary antibody and human antibody bound to the dsDNA coated plate. A TMB substrate is added, and a blue color is generated. The depth of color is relative to the amount of the human anti-pathogen antigen antibody present. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

The Positive Control consists of an anti-Double Stranded DNA (dsDNA) antibody. A biotinylated anti-Positive Control antibody is added to the Positive Control wells and treated identically to the samples. The intensity of the resulting color (measured at 450 nm) is used as a calibration curve for interpretation purposes in the different assays.
