Radtape is an easy way to permanently label membranes, dried gels, and their corresponding autorads.
Radtape's phosphorescent, adhesive labels may be cut to the specific size and shape needed for each individual membrane or dried gel. An ordinary pen may be used to mark the label using the investigator's own codes and symbols. The custom label may then be peeled from its backing and affixed to the membrane or gel. Once placed against film, Radtape exposes a negative image of the markings directly onto the autorad, thus producing a permanent record to the experiment.
