This marking pen has a 3 mm tip and has been designed to provide a thin film-like barrier when a circle is drawn around the specimen on a slide. It is suitable for larger sections on slides. This barrier creates the proper surface tension to hold an antibody solution within the target area on the slide, allow for use of less reagent. The barrier formulation is insoluble in alcohol and acetone, but can be removed by xylene after the staining procedure is completed. About 500 uses.
