3,3'-Diaminobenzidine (DAB) tablets for peroxidase visualisation, SIGMAFAST™, Sigma-Aldrich®
Dodavatel: Merck
Developed for use in immunohistology and immunoblotting as a precipitating substrate for the localization of peroxidase activity. DAB is the immunohistology substrate of choice as it produces an intense brown-black stain which is resistant to alcohol. Slides stained with DAB may be dehydrated, mounted in resinous media, and stored for future reference.
SIGMAFAST™ DAB Tablets require no additional buffers or steps to prepare an active substrate solution.
Each tablet set dissolved in deionized water yields a ready-to-use buffered solution containing DAB and urea hydrogen peroxide.
Balení: Tablets are individually packaged in foil packets.
Upozornení: Hazardous - please see SDS for details. Store the tablets at –20 °C.
