Coupling of a biotin moiety to proteins allows sensitive detection of those proteins with a variety of commercially available avidin or streptavidin conjugates. This unit presents protocols for biotinylation of cell-surface proteins and proteins in solution. A major advantage of these techniques is that they do not require use of radioisotopes (although use of radioiodinated streptavidin is optional for biotin detection).
