Description

FITC-polysucrose 400 kDa is a high molecular weight, green-fluorescent tracer used in macromolecular diffusion, extracellular volume, and retention studies. Ideal for modeling transport barriers in complex biological systems.

  • Product Overview: FITC-polysucrose is a high molecular weight, water-soluble fluorescent tracer based on polysucrose labeled with fluorescein isothiocyanate (FITC). Offering bright green fluorescence and excellent biocompatibility, FITC-polysucrose is ideal for studies involving permeability, molecular diffusion, vascular barrier function, and biological transport models. Its stability and non-toxicity make it suitable for both live-cell experiments and tissue models.
  • Features:
    • Green Fluorescence: Excitation maximum at 495 nm and emission maximum at 519 nm, compatible with standard FITC filter sets.
    • High Molecular Weight Options: Available in different sizes (e.g., 20 kDa, 40 kDa, 70 kDa, 100 kDa, 400 kDa) to match diffusion and permeability requirements.
    • Water-Soluble and Biocompatible: Fully soluble in aqueous solutions, suitable for biological systems without inducing cytotoxicity.
    • Bright and Stable Labeling: FITC conjugation provides durable fluorescence for both real-time tracking and fixed endpoint studies.
    • Minimal Non-Specific Binding: Maintains clear background and reliable signal detection in complex biological environments.
  • Benefits:
    • Reliable Molecular Diffusion Tracking: Models macromolecule behavior across biological barriers and in engineered systems.
    • Ideal for Permeability Assays: Commonly used to assess tight junction integrity, vascular leakage, and epithelial barrier function.
    • Supports Live-Cell and Fixed-Cell Imaging: Suitable for both dynamic real-time experiments and post-fixation endpoint analysis.
    • Flexible Use in Diverse Systems: Applied in microfluidic platforms, organ-on-chip models, perfused tissues, and 3D constructs.
    • Bright Fluorescence for Easy Quantification: Ensures sensitive and reproducible detection across imaging and plate reader platforms.
  • Applications:
    • Permeability and Barrier Integrity Studies: Used in epithelial, endothelial, and blood-brain barrier models to assess transport properties.
    • Tracer Studies in Microfluidics and Bioreactors: Visualizes molecular transport in flow-based systems.
    • Live and Fixed Imaging Applications: Tracks distribution of macromolecules in live-cell or fixed-tissue experiments.
    • Diffusion and Transport Modeling: Supports research into size-dependent molecular movement in biological and synthetic systems.
  • Technical Specifications:
    • Fluorescence: Excitation maximum at 495 nm, emission maximum at 519 nm.
    • Molecular Weights: Available in multiple sizes, including 20 kDa, 40 kDa, 70 kDa, 100 kDa, and 400 kDa.
    • Appearance: Light-sensitive, greenish dry powder, readily soluble in water.
    • Labeling: Optimized degree of labeling to ensure bright fluorescence while maintaining polysucrose behavior.
  • Storage and Stability:
    • Store dry and protected from light at 2°C to 8°C for optimal stability and fluorescence retention.
    • Stable under recommended conditions for extended periods without significant loss of performance.
  • Packaging and Availability:
    • Supplied as dry powder to maximize stability and handling ease.
    • Available in multiple research-grade packaging sizes to support both small-scale and larger experimental needs.
