1-Step™ NBT/BCIP Substrate Solution

Description

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
