Nitro blue tetrazolium chlorideanalytical grade
(NBT, Nitro BT, Nitrotetrazolium blue chloride, Ditetrazolium dye)
C40H30Cl2N10O6 • Mr 817.7 • CAS [298-83-9]
The ditetrazolium compound nitro blue tetrazolium chloride, also known as NBT
for short, serves as a substrate for the detection of succinate dehydrogenase
(1), glucose-6-phosphate dehydrogenase (2) and xanthine oxidase (3). NBT is
used in conjunction with BCIP (cat. no. 15247) for the colourimetric detection
of alkaline phosphatase labelled molecules in Northern, Southern and Western
blotting, in situ hybridisation and immunohistochemistry. When incubated with
alkaline phosphatase, the BCIP/NBT substrate produces an insoluble,
violet-stained NBT-diformazan precipitate that is easily detected on membranes
or tissue sections.
BCIP p-toluidine salt and NBT should be dissolved in
dimethylformamide to prepare a stock solution.
For added convenience,
ready-to-use BCIP/NBT solutions are offered: SERVAColor BCIP/NBT Blot
Solution, cat. no. 15245 and BCIP/NBT Ready-to-use Substrate for
Immunohistochemistry and Blotting, cat. no. 15246.
Stock solution
for Western blots: 66 µl NBT stock solution and 33 µl BCIP stock solution
in 10 ml staining buffer (100 mM NaCl, 5 mM MgCl
2, 100 mM Tris; pH
9.5).
