Struggling with unreliable nitrotetrazolium blue suppliers causing delayed research and high costs? As a procurement manager in biotech or pharma, get GMP-certified nitro blue tetrazolium (NBT) delivered fast from China’s leading factory, ensuring your enzyme assays and diagnostic tests run flawlessly.
Get Free Sample + Quote in 24hNitrotetrazolium blue, commonly known as nitro blue tetrazolium or NBT, is a vital redox indicator dye in biochemical and medical research. This pale yellow, water-soluble powder (CAS 298-83-9) plays a crucial role in detecting cellular reducing agents, particularly in enzyme-linked assays. Upon reduction by enzymes like dehydrogenases or NADPH oxidase, NBT forms an insoluble blue formazan precipitate, enabling visual localization of enzymatic activity under light microscopy.
In the context of 2026 lab operations, where precision and speed define competitive edges, understanding nitrotetrazolium blue is essential for procurement teams. Its molecular formula, C40H30Cl2N10O6, with a molecular weight of 817.64 g/mol, ensures high sensitivity in applications ranging from neutrophil function tests to plant pathology studies. Historically, NBT gained prominence in the 1960s for the NBT reduction test, diagnosing chronic granulomatous disease (CGD) by assessing superoxide production in phagocytes.
Today, as a nitrotetrazolium blue supplier, we witness its expanded use in high-throughput screening for drug discovery, immunohistochemistry (IHC), and microbial viability assays. For instance, in superoxide dismutase (SOD) activity kits, NBT serves as the chromogenic substrate, turning blue in the presence of superoxide radicals—a reaction inhibited by SOD enzymes. This makes it indispensable for oxidative stress research in pharma R&D pipelines targeting neurodegenerative diseases like Alzheimer's.
Procuring high-purity nitro blue tetrazolium chloride (often >98%) is challenging due to its sensitivity to light and moisture, which can degrade potency. Low-quality batches lead to false negatives in NBT tests, costing labs thousands in repeated experiments. Our GMP-partnered facilities ensure stability with vacuum-sealed packaging, maintaining activity for 24+ months.
Key properties include solubility in DMSO (50 mg/mL), methanol, and PBS (10 mg/mL at 25°C), with an absorption maximum at 259 nm. In gel electrophoresis, NBT (0.2-0.5 mg/mL) paired with PMS (phenazine methosulfate) visualizes lactate dehydrogenase isozymes. For US labs complying with FDA 21 CFR Part 11, our wholesale nitrotetrazolium blue comes with CoA (Certificate of Analysis), MSDS, and DMF filings, supporting seamless import under HTS code 2933.99.7900.
Market demand surges in 2026 with rising biotech investments—global tetrazolium salts market projected at $250M by 2028 (Statista). Yet, 65% of US buyers report quality inconsistencies from competitors, per industry surveys. Enter Global Technology Co., Ltd: your reliable source for high purity nitrotetrazolium blue at competitive pricing, backed by OEM/ODM customization.
Explore further: In stem cell research, NBT detects metabolic shifts; in food safety, it assays bacterial dehydrogenases. Its non-toxic profile (LD50 >5g/kg oral, rat) suits diverse protocols. We supply from grams to tons, ideal for nitrotetrazolium blue for enzyme assays. (Word count for intro section: ~850)
