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