Newcomer Supply PAP Pen Liquid Blocker creates a secure boundary on glass and plastic around a tissue specimen for IHC procedures.

Newcomer Supply PAP Pen Liquid Blocker, hydrophobic slide markers for staining procedures, creates a visible hydrophobic barrier that provides proper surface tension to hold reagents within a targeted area when applied around tissue sections or smears on a microscopic slide. This surface tension ensures the amount of reagent needed for sufficient reaction is reduced and retained for complete tissue section coverage. Multiple specimens can be separated by drawn circles or lines applied to the same slide. PAP Pen Liquid Blockers contain a unique formulation that is water repellent, insoluble in alcohol and acetone, soluble in xylene and temperature resistant up to 120°C. Also available in PAP Pen Liquid Blocker, Mini which provides a finer pen tip for drawing a thinner barrier film.
