BCIP/NBT 50X

$289.00

Product Description

5-bromo, 4-chloro, 3-indolylphosphate (BCIP)/Nitro-Blue Tetrazolium (NBT) substrate, used for the localization of alkaline phosphatase (AP) labeled probes on Western, Northern, Southern and dot blots. BCIP acts as the substrate for AP and reacts further after the dephosphorylation to give a dark-blue indigo-dye as an oxidation product; NBT serves herein as the oxidant and also gives a dark-blue dye, intensifying the color and making the detection more sensitive.
