Description:
Methyl 4-bromo-3,5-dichlorobenzoate, Purity: 97%, CAS Number: 117738-81-5, Appearance: Solid or Semi-solid or liquid or lump, Storage: Sealed in dry, Room Temperature, Size: 5g
Description:
Fluorescein Sodium is a synthetic organic compound that is a common fluochrome dye. It is obtained from the condensation of phthalic anhydride with resorcinol on heating. It is used in dying silk and wool, ink manufacturing, in coloring cosmetics, and in coloring gasoline and as a toner. It is widely used as a fluorescent tracer for many applications. It appears as a yellowish (yellowish-red) to red solid crystalline powder that is soluble in acetone, methanol, hot alcohol, glacial acetic acid, alkali hydroxides, carbonates and water.
Description:
Dihydrofluorescein diacetate (also called fluorescin diacetate) is hydrolyzed by cellular esterases to dihydrofluorescein (also called fluorescin) and is then oxidized to fluorescein primarily by H2O2.
Description:
2,5-Dioxopyrrolidin-1-yl 4-(3-(trifluoromethyl)-3H-diazirin-3-yl)benzoate, Purity: 97%, CAS Number: 87736-89-8, Appearance: Solid, Storage: Keep in dark place, Inert atmosphere, Store in freezer, under -20 C, Size: 250mg
Description:
DAF-2 is highly sensitive reagent for NO detection and determination of nitric oxide synthase activity. DAF-2, however, remains essentially nonfluorescent until it reacts with the nitrosonium cation (produced by spontaneous oxidation of nitric oxide) to form a fluorescent heterocycle, which becomes trapped in the cell's cytoplasm. This sensitive fluorescent probe has been used to identify individual nitric oxide-producing neurons in brain slices, in mitochondria and in living plant cells. Spectral data: lambdaex 505nm; lambdaem 518nm in 0.1M Tris pH8.0.
