Description
- Product Overview: Eosin Y-dextran is a water-soluble conjugate of dextran with the fluorescent dye Eosin Y. It is primarily used for permeability studies, flow tracking, and visualization of biological barriers. The strong absorbance and emission in the visible spectrum make it useful for imaging in cell biology, vascular research, and analytical applications. Available in a range of molecular weights, Eosin Y-Dextran offers flexibility for various experimental setups.
- Features:
- Visible Range Fluorescence: Exhibits strong absorption around 517 nm and fluorescence emission around 540 nm, making it easily detectable with standard optical setups.
- Water-Soluble: The dextran backbone ensures excellent solubility in aqueous solutions, simplifying preparation and use in biological systems.
- Available in Multiple Molecular Weights: Eosin Y-dextran is offered in a variety of sizes to match different permeability and diffusion study needs.
- Stable and Biocompatible: The conjugate retains the known biocompatibility of dextran, supporting use in live cell, tissue, and model system experiments.
- High Lot-to-Lot Consistency: Manufactured under controlled conditions to ensure reproducibility in experimental results.
- Benefits:
- Ideal for Permeability Studies: Enables clear visualization of barrier integrity and molecular transport across cellular or tissue layers.
- Supports Flow and Diffusion Tracking: The stable fluorescence makes it useful for tracking molecular movement in microfluidics, perfusion systems, and in vivo models.
- Suitable for Live Imaging: Non-toxic properties of the dextran carrier make it applicable for live-cell assays and tissue imaging.
- Flexible Application Range: Choice of molecular weight allows researchers to tailor experiments based on desired diffusion rates and molecular size exclusions.
- Reliable Signal Detection: Strong visible fluorescence simplifies imaging without the need for specialized UV-excitation equipment.
- Applications:
- Barrier Permeability Assays: Used to assess tight junction integrity, vascular leakage, and epithelial permeability.
- Flow and Transport Studies: Applied in dynamic systems like microfluidic devices and perfusion bioreactors to trace fluid and molecular transport paths.
- Visualization in Tissue and Cell Models: Used to map molecular distribution in tissues or during experimental treatments in cell culture.
- Analytical Methods: Employed as a molecular marker in experimental setups requiring bright, visible fluorescence for flow tracking or diffusion monitoring.
- Technical Specifications:
- Fluorescence: Absorbance maximum about 517 nm, emission maximum about 540 nm.
- Molecular Weights: Available in various sizes to suit experimental needs (e.g., 10 kDa, 500 kDa).
- Appearance: Supplied as a red to orange powder, readily soluble in water.
- Storage and Stability:
- Store dry in a sealed container at ambient temperature.
- Protect from light to maintain optimal fluorescence intensity and product stability.
- Packaging and Availability:
- Supplied as dry powder for easy handling and long-term storage.
- Available in research-grade packaging sizes suitable for both small experiments and larger study series.
