Description

Fluorescein W/S CAS: 518-47-8 | MF: C20H10O5•2Na | MW: 376.27, Buy now for reliable and reproducible results from Tristains.

Fluorescein W/S is an organic fluorescent dye that belongs to triarylmethine dyes and has a tricyclic structural framework of xanthine. It comes in the form of a dark orange to red powder that has a good solubility rate in water. Fluorescein W/S is a chemically modified version of fluorescein, which has been chemically modified to improve its solubility in water. This increased aqueous solubility has been made possible by the incorporation of a water-soluble functional group in the fluorescein molecule by the addition of a sulfonate (–SO3H) or carboxylate (–COOH) functional group. These structural changes enable Fluorescein W/S to be stable and easily soluble in aqueous conditions.

Applications

  • Fluorescein W/S is also a popular fluorescent tracer in imaging methods, which enable a researcher to view the biological structures and processes in real-time.
  • It is commonly applied in microscopy of samples in the laboratory to increase the level of contrast so that the cellular components can be visualized and the molecular interactions observed more easily.

Key features

  • Enhanced Water Solubility: Particularly adapted to be dissolved in aqueous solutions more easily than the regular fluorescein.
  • Bright & Stable Fluorescence: Delivers high-contrast biological imaging with intense and stable fluorescence.
  • Versatile Applications: Application Suitable in research studies, microscopy, cytology, histology, and analysis.
  • Reproducible Results: Provides assays and experiments with consistent and reliable results.

General Description

Fluorescein W/S is a water-soluble fluorescent dye that is designed to give precise and consistent laboratory measurements. Its improved solubility and stability have seen it become an essential reagent in fluorescence-based biological imaging, microscopy and analytical testing. The dye not only gives a superior visual ability to visualize the cell structures, but it also allows tracking of the biological processes in real-time and gives consistent performance in both research and teaching laboratories. Fluorescein W/S is reliable, stable, and cost-effective to every laboratory in the USA. Its versatility and fluorescence capabilities render it a necessary reagent in scientific and analytical procedures.

Fluorescein sodium salt is a disodium salt of fluorescein and a noted pH sensitive fluorophore. Fluorescein sodium salt has been utilized in studies as a drug model, as a penetrating dye and also as a fluorescein tracer. Fluorescein sodium salt has also been used in vitro to quantify root dentin demineralization. Additional reported uses include microscopy, as a gain medium in dye laser use and to detect latent blood stains in vitro. Common derivatives of Fluorescein include fluorescein isothiocyanate (FITC), eosin and Rose Bengal (sc-296278) and Rose Bengal sodium salt (sc-203757)
