Description

Tritc-lysine-dextran 70 kDa is a red-fluorescent tracer used in macromolecular diffusion, permeability, and cellular uptake studies. The lysine modification supports stable conjugation for imaging and molecular tracking in biological systems.

  • Product Overview: TRITC-lysine-dextran is a water-soluble dextran modified with lysine groups and covalently labeled with tetramethylrhodamine isothiocyanate (TRITC). It offers bright red-orange fluorescence combined with enhanced conjugation and fixation capabilities through the lysine amine groups. TRITC-lysine-dextran is ideal for molecular tracking, permeability studies, and stable labeling in live-cell and fixed-cell imaging applications.
  • Features:
    • Red-Orange Fluorescence: Excitation maximum at approximately 555 nm and emission maximum at approximately 580 nm, compatible with TRITC filter sets.
    • Lysine Modification: Provides additional amine groups, supporting enhanced conjugation and stronger fixation after labeling.
    • Water-Soluble and Biocompatible: Fully soluble in aqueous systems and compatible with biological environments.
    • Stable TRITC Labeling: Bright and durable fluorescence for dynamic tracking and endpoint assays.
    • Available Across Multiple Sizes: Offered in various molecular weights tailored to diffusion and permeability applications.
  • Benefits:
    • Improved Fixation Performance: Lysine groups enhance crosslinking during paraformaldehyde fixation, preserving fluorescence for fixed-cell imaging.
    • Reliable Live and Fixed Tracking: Suitable for studying real-time molecular movement and long-term fixed samples.
    • Supports Surface Conjugation Studies: Facilitates binding to biomolecules and functionalized materials through available amine groups.
    • Strong Signal in Complex Systems: Red-orange fluorescence ensures easy detection in tissue, cell, and fluidic models.
  • Applications:
    • Permeability assays across biological barriers.
    • Intracellular transport and endocytosis research.
    • Surface binding and conjugation experiments.
    • Live-cell imaging and fixed-tissue analysis.
    • Tracer studies in perfusion systems and engineered tissues.
  • Technical Specifications:
    • Fluorescence: Excitation maximum approximately 555 nm, emission maximum approximately 580 nm.
    • Backbone: Dextran modified with lysine groups and labeled with TRITC.
    • 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 long shelf life and convenient handling.
    • Available in research-grade packaging sizes to suit different experimental needs.
