Information d'application

Plaque: Pre-coated

Protocole: This COVID19 human IgA antibody ELISA kit employs an indirect ELISA method. In this kit, standard 96-well plates (12 strips with 8 wells/strip) are coated with the SARSCoV-2 N protein, which combines with the corresponding antibody present in a sample. When a secondary anti-human Antibody-HRP is added, a complex of Antibody-HRPhuman IgA antibody-virus N antigen forms on the microplate. A TMB substrate is added and a blue color is generated. The depth of color is relative to the amount of the anti-SARS-CoV-2 IgA antibody present. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Procédure de l'essai:

1. Prepare all reagents, samples and standards as instructed.
2. Add 100 μL positive control or sample to each well. Incubate 1.5 hours at room temperature.
3. Add 100 μL prepared HRP- anti positive control IgG Antibody and/or 100 μL of prepared HRP-anti Human IgG Antibody to each well. Incubate 1 hour at room temperature.
4. Add 100 μL TMB One-Step Substrate Reagent to each well. Incubate 10 minutes at room temperature.
5. Add 50 μL Stop Solution to each well. Read at 450 nm immediately.
6. Read at 450 nm immediately.
