| 11-Nitrogen dioxide (as nitrite) | 11-Nitrogen dioxide (as nitrite). Uses: For analytical and research use. Group: Environmental proficiency testing. Catalog: APS014189. Format: 4 x Palmes-type diffusion tubes spiked with sodium nitrite as a surrogate for Nitrogen dioxide (NO2). |  |
| cyanase | This enzyme, which is found in bacteria and plants, is used to decompose cyanate, which can be used as the sole source of nitrogen. Reaction (1) can be considered as the reverse of 'carbamate = cyanate + H2O', where this is assisted by reaction with bicarbonate and carbon dioxide (see mechanism above), and hence is classified in sub-subclass 4.2.1. Bicarbonate functions as a recycling substrate. Group: Enzymes. Synonyms: cyanate lyase; cyanate hydrolase; cyanate aminohydrolase; cyanate C-N-lyase; cyanate hydratase. Enzyme Commission Number: EC 4.2.1.104. CAS No. 37289-24-0. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4943; cyanase; EC 4.2.1.104; 37289-24-0; cyanate lyase; cyanate hydrolase; cyanate aminohydrolase; cyanate C-N-lyase; cyanate hydratase. Cat No: EXWM-4943. |  |
| (±)-γ-Tocopherol | (±)-γ-Tocopherol is a form of vitamin E with antioxidant and anti-inflammatory properties. It traps and detoxifies reactive nitrogen oxide species, including nitrogen dioxide, in cell-free assays. Uses: Antioxidants. Synonyms: 7,8-Dimethyltocol; all-rac-γ-Tocopherol; DL-γ-Tocopherol; 3,4-dihydro-2,7,8-trimethyl-2-(4,8,12-trimethyltridecyl)-2H-1-benzopyran-6-ol. Grade: ≥95%. CAS No. 7616-22-0. Molecular formula: C28H48O2. Mole weight: 416.68. |  |

Appearance: White To Light Yellow-Colored, Free-Flowing Powder. Storage: Recommend storage at refrigeration (4 °C) or frozen temperature (-18 °C) in original, sealed package until processed. Form: Powder. Antiallergic Formula, Female Vaginal Health Formula. Cat No: PRBT-023. | |
| TMB | TMB is a non-toxic, non-mutagenic, colorless dye that is also used as a chromogenic agent in enzyme detection systems based on horseradish peroxidase (HRP). TMB can function as a photoacoustic probe for reactive oxygen and nitrogen species ( ROS/RNS ), reacting with hypochlorite, hydrogen peroxide, singlet oxygen, and nitrogen dioxide to produce blue oxidation products. TMB can detect the singlet oxygen produced by the outer membrane of Escherichia coli ATCC 25922 [1] [2]. Uses: Scientific research. Group: Fluorescent dye. Alternative Names: BM blue; Sure Blue TMB. CAS No. 54827-17-7. Pack Sizes: 10 mM * 1 mL; 500 mg; 1 g; 5 g. Product ID: HY-15930. |  |
| TMB dihydrochloride | TMB dihydrochloride is the dihydrochloride form of TMB (HY-15930). TMB dihydrochloride is a non-toxic, non-mutagenic, colorless dye that is also used as a chromogenic agent in enzyme detection systems based on horseradish peroxidase (HRP). TMB dihydrochloride can function as a photoacoustic probe for reactive oxygen and nitrogen species (ROS/RNS), reacting with hypochlorite, hydrogen peroxide, singlet oxygen, and nitrogen dioxide to produce blue oxidation products. TMB dihydrochloride can detect the singlet oxygen produced by the outer membrane of Escherichia coli ATCC 25922 [1] [2]. Uses: Scientific research. Group: Fluorescent dye. Alternative Names: BM blue dihydrochloride; Sure Blue TMB dihydrochloride. CAS No. 64285-73-0. Pack Sizes: 10 mM * 1 mL; 500 mg; 1 g; 5 g. Product ID: HY-15930A. | |
| Urine, Normal | Human Urine formation helps to maintain the balance of minerals and other substances in the body. For example, excess of calcium is normally eliminated through the urine. Urine also excretes ammonia, the build-up of which is harmful to the body. Human urine is the result of a mechanism that maintains the appropriate amount of water in the body. When it leaves the body, Human urine is usually around pH 6, though it may be as low as 4.5 or as high as 8.2. As urea, the compound which accounts for 75-90% of the nitrogen in urine begins to decay, hydroxide ions form, raising the pH as high as 9-9.3. The decay of urea into carbon dioxide is catalyzed by urease. Group: Biologicals. Pack Sizes: 1L. US Biological Life Sciences. |  Worldwide |
