The PAP Pen is an optimized hydrophobic slide marker that creates a film-like barrier around tissue specimens ensuring only the necessary amount of antibody is needed is used. By creating a film-like barrier that creates the ideal surface tension for holding antibodies within the targeted area of a slide over-flooding slides and wiping excess fluid around specimens is no longer necessary. This PAP Pen contains a special formulation that is water repellent, insoluble in alcohol/acetone, and stable for long periods of time. *** Not suitable when using buffers that contain formamide.
