Fluorescein W/S CAS: 518-47-8 | MF: C20H10O52Na | MW: 376.27, Buy now for reliable and reproducible results from Tristains at Chemical World.
Fluorescein W/S is an organic fluorescent dye of the triarylmethine group with xanthine tricyclic structure. It is supplied in dark orange to red powder and it is very soluble in water. It is a chemically conjugated version of fluorescein that enhances water solubility with the addition of water-soluble functional groups like sulfonate or carboxyl functional groups. These additions increase the solubility and stability in aqueous solutions making Fluorescein W/S very useful in fluorescence-based applications in laboratories.
Applications
- Fluorescein W/S is commonly used as a fluorescent tracer in imaging techniques, allowing researchers to observe biological structures and processes in real time.
- It is also common in laboratory microscopy to increase the contrast of the sample so that cellular components and molecular interactions can be seen much more clearly.
Key features
- Enhanced Water Solubility: Particularly altered to be more soluble in aqueous solution than normal fluorescein.
- Bright & Stable Fluorescence: Provides high-contrast biological imaging with intense and stable fluorescence.
- Versatile Applications: Applicable in research studies, microscopy, cytology, histology, and analysis.
- Reproducible Results: Provides steady and dependable results between assays and experiments.
General Description
The fluorescein W/S is a water-soluble fluorescent dye designed to be used reliably in the laboratory.
