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.
