Improves section attachment to glass slides during immunohistochemical staining. It creates a sticky surface on the glass slide ideally suited for paraffin or frozen section attachment. Greatly improves section adherence throughout immunostaining protocols. It can be used in conjunction with the Liquid Blocker Super Pap Pen Liquid Blocker or the Mini Pap Pen.
Provides a sticky membrane on slide
Prevents the tissue from moving, wrinkling or falling off the slide
Flattens the section and eliminates the need for hot water extension
The latest PAP Pen is still a superior hydrophobic liquid that creates a secure boundary on glass and plastic around a tissue specimen during IHC procedures. The fluid flows as a light blue on the slide and easier to see than the original (clear) PAP pens.
