ready-to-use hydrophobic barrier pens
PAP Pens are used for immunohistochemical applications. The hydrophobic properties allow the user to draw barriers on the slide, in any pattern, to confine the flow of reagents to a defined area. A minimum of valuable antiserum will be used. Visible marking is light green/blue and can be removed with Xylene.
For immunohistochemistry, the PAP Pen should be applied after deparaffinization.
