3012-71-3 - Introduction
fluorescein isocyyanate isomer ii(Fluorescein isocyyanate isomer II) is a fluorescent dye. The following is a description of its nature, use, preparation and safety information:
1. Nature:
-chemical formula: C21H11O5N2S
-Molecular weight: 389.39g/mol
-Appearance: Yellow crystalline powder
-Solubility: Soluble in organic solvents, such as dimethyl sulfoxide (DMSO), Dimethyl Formamide (DMF), etc.
-Fluorescence characteristics: Under ultraviolet light (excitation wavelength is about 490 nm), the fluorescence emission peak is about 520 nm
2. Use:
-Cell and molecular biology research: can be used for chromosome markers, protein, antibody or nucleic acid coupling, and intracellular and intercellular tracing
-Immunofluorescence staining: suitable for immunohistochemical staining and flow cytometry
-Fluorescent probes: widely used in biological imaging and fluorescence microscopy research
3. Preparation method:
The general preparation method is synthesized by reacting fluorescein with isothiocyanate. Specific preparation methods may vary, but the main steps include obtaining fluorescein acid, which is then reacted with isothiocyanate to form fluorescein isothiocyanate isomer ii.
4. Safety Information:
- fluorescein isothiocyanate isomer ii may release toxic fumes under flammable conditions.
-Use with care to avoid contact with skin, eyes and taking.
-Wear appropriate protective equipment such as lab gloves, goggles and lab coats during operation.
-storage should be sealed in a cool and dry place, away from fire and high temperature.
-Detailed safety information can be obtained in the product manual or in the safety data sheet provided by the supplier.
