Product details:
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.
