Fast Red TR Salt 1,5-naphthalenedisulfonate salt is a chromogenic compound employed in the detection of enzymatic activity, particularly in histochemical staining procedures. In research, it is used to localize the presence of alkaline phosphatase activity within tissue sections, cells, or on electrophoresis gels by producing a red precipitate upon reaction with the enzyme. This staining method is important for studying gene expression patterns and for identifying specific cell populations based on enzyme markers. The disulfonate groups in Fast Red TR Salt 1,5-naphthalenedisulfonate salt enhance its water solubility, which is for its application in aqueous staining protocols. Research involving this compound contributes to a deeper understanding of cellular differentiation and function. Additionally, it is instrumental in the field of molecular biology, where it aids in the visualization of nucleic acid sequences through in situ hybridization techniques.
