This is a great question to test your technical knowledge of Western Blotting. Just to review quickly, Western Blots are a method of detecting one specific protein of interest out of a mixture of proteins. The steps involved in Western Blotting are as follows:

1. Separate the mixture of proteins using SDS-PAGE (polyacrylamide gel electrophoresis).

2. Transfer the proteins from the gel to a nitrocellulose membrane using another electrophoresis.

3. Incubate the nitrocellulose membrane with a primary antibody that will specifically bind and recognize the protein you are interested in.

4. Incubate the nitrocellulose membrane with a secondary antibody that is conjugated (linked) to an enzyme. This antibody will recognize and bind to the primary antibody-protein of interest complex. The enzyme that is bound to the secondary antibody ...
