You are a researcher interested in studying the cytoskeleton. How can you use antibodies to locate actin- and tubulin-containing structures?
Since those cytoskeletal components are proteins, it is possible to immunize an animal with foreign proteins isolated from tissues. For example, a rabbit could be immunized with the actin and tubulin purified from tissues of the chicken, a very distant relative of the rabbit. Those antibodies could be purified from the rabbit's blood and then linked to fluorescent tags. When the cells are exposed to the anti-actin and anti-tubulin antibodies, they will stick to those molecules in the cell. If different colored dyes were used to tag the antibodies, it would be possible to localize those cytoskeletal proteins in the same cell.
