Invignome’s hydrophobic barrier pens for Immunology.

Our goal is to provide you the best user-friendly hydrophobic blocker!

PAP pens contain a glass or plastic slide adherent hydrophobic liquid. The Pap Pen are used to circle around a tissue specimen prior to IHC/IFA procedures. 

What is so special about Invignome’s Pap Pens?

Most generic Pap Pen formulations deteriorated by the fixatives and detergents used in every immunohistochemistry or immunoflourescence. Invignomes unique Pap Pen formulation is insensitive to these reagents. Our Pap Pen applicators – called the GnomePens – are unique and have a clear body.

The GnomePens advantages

• Stable using Paraformaldehyde and Formaldehyde (formalin) fixatives.
• Stable using detergents like Triton X100 or X114 and Tween20
• No interference with flourophores and antibodies
• Choose – a wide or thin line to fit your experimental needs
• Color coded – differentiate between antibodies, samples and controls
• All our products have a long shelflife – 18 months.
