Application

SIGMAFAST Fast Red TR/Naphthol AS-MX Tablets has been used:
  • in alkaline phosphatase staining in organ sections
  • for staining chondrogenic spheroids in immunohistochemistry studies
  • for the detection of hybridization signals in in situ mRNA hybridization studies of human palatine tonsils sections

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 dissolved in 1 mL deionized water yields a ready-to-use buffered solution.

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.
