The Chikungunya Virus E2 Protein Mouse IgG ELISA Kit employs an indirect ELISA method. In this kit, standard 96-well plates (12 strips with 8 wells/strip) are coated with E2 protein, 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 HRP Conjugated secondary anti-Mouse IgG antibody is added, a complex forms between HRP conjugated secondary antibody and Mouse antibody bound to the protein coated plate. A TMB substrate is added, and a blue color is generated. The depth of color is relative to the amount of the Mouse anti-E2 antibody present. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

1. Prepare all reagents, samples and standards as instructed.
2. Add 100 µL positive control, or sample to each well. Incubate 1 hour at room temperature.
3. Add 100 µL prepared HRP Conjugated Anti-Mouse IgG Antibody into respective wells. Incubate 1 hour at room temperature.
4. Add 100 µL TMB One-Step Substrate Reagent to each well. Incubate 10 to 30 minutes at room temperature.
5. Add 50 µL Stop Solution to each well. Read at 450 nm immediately.
