Immunological detection of proteins is an essential method to demonstrate to undergraduate biology students, however, is often difficult in resource and time poor student laboratory sessions. This method describes a failsafe method to rapidly and economically demonstrate this technique using biotinylated proteins or biotin itself as targets for detection. This negates the need for a specific primary antibody, saving cost and time. In addition, the easily available and safe reagents allow the methods to be readily adopted without specialist technical expertise. As a result, staff can confidently transfer ownership of the task to the student so as to also develop scientific inquiry skills which promotes student motivation and engagement.
