The key reagent used in ELISA (Enzyme-Linked Immunosorbent Assay) to detect viruses is an antibody. This antibody is specific to the virus being tested for and is used to capture and detect the presence of the virus in a sample.

Here are the steps:

1. Coating: The first step in an ELISA assay is coating the wells of a microplate with a capture antibody. This antibody is specific to the virus being tested for.

2. Blocking: After the coating step, the plate is blocked to prevent non-specific binding.

3. Sample Addition: The sample suspected of containing the virus is added to the wells. If the virus is present, it will bind to the capture antibody.

4. Detection: A detection antibody is added, which binds to the virus, forming an antibody-antigen-antibody "sandwich."

5. Substrate Addition: A substrate is added, which is converted by the enzyme linked to the detection antibody into a detectable signal, usually a color change.

6. Reading the Results: The plate is read on an ELISA reader. The intensity of the color is proportional to the amount of virus present in the sample.
