Application

SIGMAFAST™ Fast Red TR/Naphthol AS-MX tablets has been used in fluorescent in situ hybridization for the analysis of gene expression in neurons and synapses.
Developed for use as a precipitating substrate for the detection of alkaline phosphatase activity in immunochemistry. Primary uses are in immunohistology, immunoblotting, or dot blotting. SIGMAFAST™ Fast Red TR/Naphthol AS-MX tablets contain 0.6 mM levamisole to block endogenous alkaline phosphatase activity. SIGMAFAST™ Fast Red TR/Naphthol AS-MX Tablets require no additional steps or buffers to prepare an active substrate solution.

Reconstitution

Each tablet set dissolved in 10 mL of deionized water yields a ready-to-use buffered solution.

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
