Technical Tip

Using a Pap-Pen

msdsarrow12Aqua-Hold Pap Pen

Aqua-Hold Pap Pen

The Aqua-Hold Pap Pen draws a liquid repellent barrier around a section of tissue. Used like a paint pen, you just draw a well on a slide. The barrier creates the proper surface tension to hold aqueous solutions such as costly antibody and other valuable specimens. After application, the barrier material is insoluble in alcohol and acetone but can be removed after staining with xylene. Each pen holds 13ml of long-lasting material, making hundreds of wells. Red tint distinguishes the well drawing on the slide to easily view.

A wide tipped pen designed for use with frozen sections. The pen provides a sticky membrane which when applied to the slide and onto which the section is placed it eliminates the section from falling off, moving, or wrinkling on the slide during immunostaining procedures. The membrane is stable up to 110°C and is suitable for vigorous applications such as in-situ hybridization.

A wide tipped pen, designed for use with paraffin sections. The pen provides a sticky membrane to the glass slide which not only prevents paraffin sections from falling off but also keeps the sections flat on the slide.

Tissue Capture Penarrow12Tissue Capture Pen

With one swift application of the EMS Tissue Capture Pen, you are able to change your plain glass slide into a coated one.

The EMS Tissue Capture Pen is a coating pen with a wide point (18mm) for fixing various tissue sections (paraffin embedded, frozen and formalin sections, etc.) The unique pen is unaffected by heat up to 120°C so it offers secure and firm adhesion of the tissue section. It may be used in Microwave staining, immunostaining, in situ etc….

One application is all that is needed, and after it is applied, allow to dry for 1-2 minutes.

The EMS Tissue Capture may be used in conjunction with our Pap-Pen (71310) and will allow for easy placement of adherent as well as nonadherent cells on a glass slide. Immunostaining/ISH can be performed by applying a few drops of tissue suspension or liquid media onto the glass slide which is circled by the Pap-Pen, and then your section can be placed.
