Invitrogen™ Dextran, Texas Red™, 3000 MW, Neutral
Description
Labeled dextrans are hydrophilic polysaccharides most commonly used in microscopy studies to monitor cell division, track the movement of live cells, and to report the hydrodynamic properties of the cytoplasmic matrix. The labeled dextran is commonly introduced into the cells via microinjection. Dextrans are hydrophilic polysaccharides characterized by their moderate-to-high molecular weight, good water solubility, and low toxicity. They also generally exhibit low immunogeniticy. Dextrans are biologically inert due to their uncommon poly-(α-D-1,6-glucose) linkages, which render them resistant to cleavage by most endogenous cellular glycosidases.
- Succinimidyl coupling of dyes to dextran molecule, which, in most cases, results in neutral or anionic dextran
- Reaction used to produce Rhodamine Green™ and Alexa Fluor™ 488 dextrans results in final product being neutral, anionic, or cationic
- Suitable for neuronal tracing (anterograde and retrograde) in live cells
- Cell lineage tracing in live cells
- Examines intercellular communications (e.g., in gap junctions, during wound healing, and during embryonic development)
- Investigates vascular permeability and blood-brain barrier integrity
- Monitoring acidification (some dextran-dye conjugates are pH-sensitive)
- Studies hydrodynamic properties of cytoplasmic matrix
- Most of the dextrans labeled with zwitterionic rhodamine B, tetramethylrhodamine, and Texas Red dyes are essentially neutral
