Identify the false statement about secondary antibodies: 1. Secondary antibodies bind to primary antibodies. 2. Secondary antibodies must be generated in the same host animal as the primary antibody was generated. 3. Secondary antibodies could be directly conjugated to HRP or use other binding proteins to localize HRP to the site of the protein of interest. 4. Fluorophores are sometimes directly conjugated to secondary antibodies and used as detection systems.

Immunofluorescence In the more common protocol for immunofluorescence detection of cellular proteins, an investigator uses two antibodies. The first binds specifically to the protein of interest. The second is labeled with fluorochromes for easy visualization, and it binds to the first antibody. In principle, one could simply label the first antibody and skip one step. Why use two successive antibodies?
