| Summary and Explanation | Nuclear Fast Red Counterstainer is designed to be used as a counterstainer after completion of immunohistochemical or in situ hybridization procedures or for routine histology. Nuclei in stained sections will be pink to light red in color. Nuclear Fast Red Counterstainer has improved stability over other formulations allowing this solution to be stored at room temperature or at refrigeration temperature (2-8°C). Other formulations tend to precipitate in cold temperatures. In addition, most formulations develop a small amount of precipitate over extended periods of time. This formulation completely eliminates the problems associated with exposure to cold and aging. | ||||||||||||||||||||||||
