Beschreibung

TRITC-dextran 4 kDa is a red-fluorescent tracer ideal for assessing tight junction permeability and paracellular transport. Its small size enables high-resolution tracking in barrier models.

  • Product Overview: TRITC-dextrans are dextran molecules covalently labeled with tetramethylrhodamine isothiocyanate (TRITC), offering bright red-orange fluorescence for permeability studies, molecular transport tracking, and live-cell imaging applications. Available in a wide range of molecular weights up to 2000 kDa, TRITC-dextrans are widely used in research on barrier function, vascular leakage, tissue diffusion, and cellular uptake.
  • Features:
    • Red-Orange Fluorescence: Excitation maximum at approximately 555 nm and emission maximum at approximately 580 nm, compatible with standard TRITC and rhodamine filter sets.
    • Wide Molecular Weight Range: Available from 4 kDa up to 2000 kDa, supporting size-dependent transport and diffusion studies.
    • Water-Soluble and Biocompatible: Fully dissolves in aqueous solutions, suitable for use in biological systems without significant cytotoxicity.
    • Stable Labeling: TRITC conjugation ensures durable fluorescence for both dynamic tracking and endpoint assays.
    • Controlled Quality: Manufactured with consistent molecular weight profiles and degrees of labeling for reproducible results.
  • Benefits:
    • Reliable Tracer for Barrier Studies: Quantitatively tracks transport across epithelial, endothelial, and engineered tissue barriers.
    • Suitable for Live-Cell and Fixed-Tissue Imaging: Bright, stable signal supports dynamic real-time imaging and fixed-sample analysis.
    • Flexible Experimental Design: Different molecular weights allow modeling of size exclusion, paracellular permeability, and tissue diffusion behavior.
    • Visible Across Multiple Platforms: Detectable with standard fluorescence microscopes, flow cytometers, and plate readers.
  • Applications:
    • Permeability assays in epithelial and endothelial models.
    • Tracking molecular diffusion in tissue engineering and microfluidic systems.
    • Vascular leakage studies in preclinical models of inflammation and cancer.
    • Intracellular transport and uptake research in live-cell studies.
    • Fluorescent labeling for tracer studies in flow and perfusion experiments.
  • Technical Specifications:
    • Fluorescence: Excitation maximum about 555 nm, emission maximum about 580 nm.
    • Molecular Weights: Available from 4 kDa to 2000 kDa.
    • Appearance: Light-sensitive, reddish-orange dry powder, readily soluble in water.
  • Storage and Stability:
    • Store dry at room temperature, protected from moisture and light.
    • Stable for extended periods under recommended storage conditions without significant loss of fluorescence.
  • Packaging and Availability:
    • Supplied as dry powder for stability and ease of use.
    • Available in a range of research-grade packaging sizes to accommodate various experimental needs.
