Application

A ready-to-use, precipitating substrate system for alkaline phosphatase. This substrate system produces an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually. Immunohistochemical staining with BCIP/NBT utilizes requires organic mounting media and can be counterstained with Nuclear Fast Red or Light Green. BCIP/NBT is generally a more sensitive method than Fast Red. Not recommended for ELISA (microwell) procedures.
BCIP®/NBT Liquid Substrate System has been used:
  • for staining alkaline phosphatase(ALP) in bone marrow stromal cells
  • as a substrate in western blot detection of matrix metalloproteinase-2 specific antibody
  • as a substrate for streptavidin-alkaline phosphatase in the enzyme-linked immunospot (ELISpot) assays

Caution

It is recommended to store the product between 4 - 8 °C. Do not freeze. The product may be stored at room temperature for up to one year. If a precipitate forms, the solution can be gently swirled or filtered.

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.

Protocols

Immunodetection Using BCIP/NBT Substrate

5-bromo-4-chloro-3-indolyl phosphate (BCIP)/nitro blue tetrazolium (NBT) is an ideal insoluble substrate for use with alkaline phosphatase. This system produces a blue-purple product. The intense color can be observed visually, is very stable, and will not fade upon exposure to light.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
