PAP PEN is a laboratory marking pen designed to create a hydrophobic barrier around tissue sections on microscope slides during immunostaining procedures. The barrier helps prevent staining reagents from overflowing across the slide surface, keeping reagents concentrated around the tissue area and helping reduce reagent consumption. Its convenient pen-style design enables precise and easy application for routine immunostaining and anatomical pathology workflows.
