PAP Pens have been improved! The new formulation of Advanced A-PAP Pens is more easily removed with xylene. Additionally, water repellency and quick-drying are slightly faster than previous liquid blockers. The protocol, volume of the tube, and the diameter of the tip remain the same.

A-PAP Pen is a ready-to-use hydrophobic barrier pen, designed for immunohistochemistry applications. A minimal amount of antibody is constrained by surface tension within a user-defined border drawn with the pen around a tissue section. The pen is stable up to 129°C in microwave heat.

This ready-to-use hydrophobic barrier pen is designed for immunohistochemistry applications. The surface tension provided by the circle, square, or any other shapes drawn to fit tissue sections with the pen, ensures that only the amount of antibody solution needed for the sufficient reaction will be applied. The pen is stable up to 129 degrees C in microwave heat.

The A-PAP Pen is an effective tool for immunostaining procedures by the Peroxidase-Antiperoxidase (PAP) method, ABC method, LSAB method, polymeric method, immunofluorescence method, ASD method, Enzyme method and Frozen Section method.

For paraffin sections, the A-PAP Pen should be applied after deparaffinization. For frozen sections, the A-PAP Pen can be applied after fixation.
