Thermo Scientific™ NBT Substrate Powder (nitro-blue tetrazolium chloride)

Description

• Thermo Scientific™ Pierce NBT and BCIP Substrates are powders and ready-made solutions of nitro-blue tetrazolium and 5-bromo-4-chloro-3'-indolyphosphate for chromogenic blot and IHC staining with alkaline phosphatase probes
• The combination of NBT (nitro-blue tetrazolium chloride) and BCIP (5-bromo-4-chloro-3'-indolyphosphate p-toluidine salt) yields an intense, insoluble black-purple precipitate when reacted with alkaline phosphatase, a popular enzyme conjugate for antibody probes
• Pierce NBT and BCIP powders are available individually and in two convenient, ready-to-use solutions (with and without a levamisole suppressor of endogenous phosphatase activity)
• Highlights: AP substrate – for detection of alkaline phosphatase (alk-phos) activity on solid media, including nitrocellulose and PVDF membranes and fixed tissue samples Chromogenic – no special equipment needed for visualization; produces purple-black precipitate that is easy to photograph Package options – choose individual NBT and BCIP powders, or preformulated, ready-to-use solutions with or without levamisole suppressor 1-Step™ NBT/BCIP Ideal for immunoblotting applications Minimal assay-to-assay variability 1-Step NBT/BCIP Plus Suppressor Ideal for staining tissues assayed with calf intestinal alkaline phosphatase without the interference caused by endogenous phosphatases Contains 1mM levamisole to inhibit endogenous phosphatase activity
