The dsRNA ELISA Kit (SKU: GXEL00361) is a quantitative sandwich ELISA for the measurement of dsRNA in plasma, serum. The assay has a detection range of 0.16 - 10 ng/mL and a sensitivity of 0.09 ng/mL.
This assay employs the quantitative sandwich enzyme immunoassay technique. An antibody specific for dsRNA has been pre-coated onto a microplate. Standards or samples are pipetted into the wells and any dsRNA present is bound by the immobilized antibody. After washing away any unbound substances, a biotin-labeled antibody specific for dsRNA is added to the wells. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of dsRNA bound in the initial step. The color development is stopped and the intensity of the color is measured.

Step
Procedure
1
Preparation: Bring all reagents and samples to room temperature and prepare reagents, working standards and samples as directed. Assay all standards and samples in duplicate.
2
Standard & Sample Incubation: Add 100 µL standard or samples to each well; incubate for 1 hour at 37 °C. Wash 3 times with Wash Buffer (300 µL).
3
Detection: Add 100 µL of Detection A (working solution) to each well; incubate for 1 hour at 37 °C. Add 100 µL of Detection B (working solution) to each well; incubate for 30 minutes at 37 °C. Wash 5 times with Wash Buffer (300 µL).
4
Color Development: Add 100 µL of Color Reagent to each well; incubate for 15 minutes at 37 °C; protect from light.
5
Stop & Read: Add 50 µL of Stop Solution to each well, then read the optical density at 450 nm within 10 minutes (correction 630 nm or 620 nm).
