    Overview

    • Product name

      PAP pen
    • General notes

      The PAP pen is a special marking pen that provides a thin film-like green-tinged hydrophobic barrier when a circle is drawn gently around a specimen on a slide. Gentle application of the pen tip while drawing is advised.

      This water repellent barrier keeps staining reagents localized on the tissue sections, prevents mixing of reagents when differentially staining two sections on the same slide, and allows use of less reagents per section.

      Insoluble in alcohol and acetone, PAP Pen markings can be optionally removed with xylene after the staining procedure is complete.

      PAP Pen is good for approximately 500 uses.

      The formulation of PAP pen has been optimised to increase water repellence and tolerance against alcohol and surface active agent, and is now a lighter colour.

    The pen works well. It`s easy to use and dries quickly. The barrier is precise and reliable - even after 24h incubation. It is resistant to buffer but can be removed with xylene.The pen is a great help in the IHC when there are multiple tissue samples on the same slide. And you save a lot of reagent, because you can frame the samples as small as possible.

    This PAP pen is very easy to use. It dries quickly. It is strong enough to create and maintain a boundary between tissue sections. I usually stain secondary antibody control on the same slide with primary antibody, so I divided the section with the PAP pen. After overnight incubation with antibody, the boundary still functional and there was no mixing between adjacent drop of solutions. Picture was taken after overnight incubation.

    PAP pen dries quickly and forms a hydrophobic layer that is not washed off by 0.1% Triton X-100 in PBS. The only concern I have is that the barrier is often difficult to dry after washing, so extra care must be taken to avoid mixing reagents between adjacent sections.

    Precise and reliable barrier pen. After application it dries rather quick and after that there's no leakage. Found it very useful for IHC when I had to isolate from each other few tissue samples on the same slide. It resists incubation in buffers with Tween-20. Soluble in Xylene.

    Asked on May 31 2012

    Answer

    The PAP pen can be used at temperatures as high as 48°C (120°F). When working with temperatures higher than 48°C, the protective barrier may be compromised and loses its water-repellant properties.

    Answer

    Thank you for your enquiry. We have not calculated the volume of liquid used per unit, however I can confirm that one unit is equivalent to drawing with the pen along the four sides of a standard IHC slide, such that a hydrophobic barrier is created to ensure the tissue remains moist upon application of antibody. I hope this information will help your customer.

    Question

    Is the PAP pen incompatible with solutions containing 50% formamide? I used a PAP pen to draw a barrier around tissue sections on glass slides, then overlaid the sections with a hybridization solution containing 50% formamide and 50% standard saline citrate (aqueous NaCl and sodium citrate). After an overnight incubation at 42 degrees in a humid chamber, some of the PAP barriers appeared to have partially disappeared--dissolved? The hybridization solution had flowed over, and there were floating green flecks (like bits of the barrier). I redrew the barrier before doing additional incubations in aqueous solutions, but the redrawn barriers seemed to have trouble adhering to the slides. I've used PAP pens before with aqueous solutions, with good results. So I wonder if the problem is the formamide.

    Asked on Apr 24 2006

    Answer

    Thank you for your enquiry. The PAP pen has been used for IHC only. You should wipe the section in a "square- coverslip" fashion if you wish to use it for ISH. (At least the size of the cover slip.) The line that is drawn must be very dry before placing a small amount of probe on the tissue. I am unsure whether formamide is a xylene solvent, however we do not believe that the PAP pen will withstand formamide;if you use the pen on the outside of the cover slip that may work. Alternatively you could try using barrier slides? Good luck with your research.

    Answer

    No, we recommend wiping the tissue dry before applying the pen to ensure the barrier does not spread across the tissue.
