We offer fluorescent kits which are based on the streptavidin-biotin
interaction so the procedures should integrate well with your current set
up. I would like to get some more information from you before I suggest a
protocol.
1. What is the antibody species (mouse, rabbit, etc) for the antibody
against one of the antigens?
2. What is the second antigen antibody species?
3. What kind of filter sets you have for your fluorescence microscope?
4. Which antigen is present in greater concentration?
