Val Fast Red Chromogen Kit

Val Fast Red Chromogen Kit consists of two solutions for the staining of formalin-fixed, paraffin-embedded (FFPE) tissues, as part of an immunohistochemistry (IHC) procedure using an alkaline phosphatase (AP) detection system on the VALENT® Automated Slide Staining Platform. The clinical interpretation of any staining or its absence should be complemented by morphological studies and proper controls and should be evaluated within the context of the patient’s clinical history and other diagnostic tests by a qualified pathologist.

Fast Red is a widely used chromogen for immunohistochemical staining. Val Fast Red is an advanced formulation of Fast Red that accelerates and intensifies staining. When in the presence of alkaline phosphatase (AP) enzyme, Val Fast Red produces a bright fuchsin-red precipitate that is insoluble in organic solvents and can be coverslipped with a permanent mounting media. Val Fast Red may also be used in multiplex detection systems, such as Val Plex 2, for Multiplex IHC applications. This product has been designed to be used on the VALENT Automated Slide Staining Platform. Mixing vials are required for each unique run of the VALENT.
