Improved Features

 In an immunohistochemistry staining, you can make a water-repellent circle around a specimen on the slide glass easily. It prevents antibody and the PBS arewashed away.

 Performance improvement made it possible to use wide range of use such as fluorescent antibody method and Immunostaining (the PAP method, the ABC method).

 The coherence to slide glass became more certain.

 Superior in water repellency. The written circle is insolubility to alcohol and acetone, dissolves in xylol.

The heat resistance improved to 120°C!
