1.What did you test for in your “blood sample” using the ELISA?

2.What is NOT an application of the ELISA test? Select one:

a. Confirm pregnancy by detecting human chorionic gonadotropin
(hCG) in urine

b. Diagnose a variety of diseases (e.g., West Nile virus, HIV,
SARS, Lyme, EBOLA) by detecting serum antibodies

c. Detect expression of the gene encoding for GFP

3.Why do you need to assay (+) and (-) control samples as well
as your experimental samples? Select one:

a. The control samples help wash off any non-specific
binding.

b. Controls help ensure that your primary and secondary
antibodies are able to bind specifically to their antigens (and not
just to the plastic or another variable).

c. Control samples help you to determine the concentration of
your sample.
