BCIP/NBT for colorimetric detection of Alkaline Phosphatase activity in membrane assays. Positive reactions form an intense blue/purple precipitate at the site of the reaction. The color develops when AP catalyzes the dephosphorylation of BCIP. The intense blue/purple precipitate is very stable and resists fading when exposed to light.
