Axol' Barrier Pen provides a heat-stable, water-repellent barrier that keeps reagents localized on tissue specimens during immunohistochemistry, immunocytochemistry, immunofluorescence, and in situ hybridization procedures and prevents mixing of reagents when multiple sections are mounted on the same slide. Stable for use with buffers with and without detergent (e.g. Tween 20 or Triton X-100, etc.). Insoluble in alcohol and acetone but is completely removed by all commonly used xylene and xylene substitute clearing agents. The barrier is compatible with enzyme or fluorescence-based detection systems. The Pen is environmentally friendly.
