What are the advantages of using secondary antibodies in indirect immunofluorescence?

1.  It makes easy to choose a different conjugate no matter the primary antibody

2. Enhance detection by localizing more conjugate at the antigen

3. Conjugation of fluorophore can interfere with the primary antibody’s recognition of the antigen
