Principle of Assay
Nuclear Fast Red is a histological staining reagent suitable for visualization of nuclei in tissue sections. Nuclear Fast Red provides a red counterstain designed for optimal performance when used in immunohistochemistry. Nuclear Fast Red is intended for use in the histologic demonstration of nuclear staining. This staining technique is used to make the critical distinction between a normal nucleus and an abnormal one. When used as a counterstain in immunohistochemical procedures, Nuclear Fast Red is compatible with most commonly used chromogens including HRP-Yellow, HRP-Green, HRP-Black, and DAB. Nuclear Fast Red is particularly useful with blue chromogens, such as HRP-Blue.
