Description
Nitrotetrazolium Blue Chloride (NBT) is a high-purity yellow crystalline dye widely used in biochemical and cell-based assays. NBT functions as an electron acceptor, forming a dark blue insoluble formazan upon reduction, making it a powerful tool for detecting enzymatic activity and cellular metabolic processes. Its reliable performance allows researchers to visualize and quantify enzyme reactions, particularly in histochemistry, cytochemistry, and microbiological studies.
Supplied as a yellow crystalline powder with high solubility in water (10 mg/mL), NBT enables consistent and reproducible results in both qualitative and quantitative assays. Its high purity (≥90% by HPLC) ensures minimal interference in experimental procedures, making it an essential reagent for laboratory research in enzymology, cell biology, and related fields.
