Liquid Blocker PAP Pen Immunohistochemistry Pen IHC Experiment Life Science Research

Product Introduction

 Liquid Blocker PAP Pen is a specialized hydrophobic marker designed for creating a liquid-repellent barrier around tissue specimens on microscope slides. This barrier effectively minimizes reagent usage while preventing sample drying and cross-contamination, ensuring optimal results in various histological and molecular biology applications.

Key Features

1. Hydrophobic Barrier Technology

• Forms a tight, water-resistant ring around tissue, reducing reagent consumption by 30–50% and preventing evaporation-induced artifacts.

2. Broad Compatibility

• Ideal for immunohistochemistry (IHC), immunofluorescence (IF), in situ hybridization (ISH), and special staining (e.g., H&E, PAS).
• Resistant to formaldehyde-based fixatives and common solvents.

3. High-Temperature Resistance

• Stable under heat treatment (up to 120°C), suitable for antigen retrieval or baking protocols.

4. Precision Application

• Fine tip allows accurate circling (1–2 mm line width) without obstructing the target area.
