dextran-40

Dextran (Dextran 40) inhibits platelet aggregation and coagulation factors, can partially replace whole blood during transfusion, and is commonly used as a plasma volume expander; it can also be used in paw edema models.

Cross-linked dextran G 200 is a hydrophilic gel designed for the separation of macromolecules based on molecular size exclusion. It operates through a gel permeation mechanism; its cross-linked structure forms a three-dimensional network with specific pore sizes, facilitating separation according to the hydrodynamic volume of molecules. This compound is utilized to regulate the partition coefficient of permeating solutes and maintain osmotic balance, and is commonly applied in gel filtration chromatography for the purification and analysis of biomacromolecules like proteins and nucleic acids. Additionally, Cross-linked dextran G 200 serves as a gel filtration medium (particle size range: 40-120 μm; spherical protein separation range: 5k-600k Da).

Cross-linked dextran G 150 is a hydrophilic gel used as a gel filtration medium, with a particle size range of 40-120 μm and suitable for separating spherical proteins within a molecular weight range of 5k-300k Da.

Cross-linked dextran G 75 serves as a gel filtration medium. It is a dextran-based matrix designed for gel filtration chromatography, featuring a particle size range of 40-120 μm. The separation range for globular proteins is 3K-80K Da, while it separates polysaccharides within the range of 1K-50K Da.

TRITC-dextran MW 40000 is a fluorescent dye with a molecular weight of 40 kD. Its excitation wavelength is 555 nm. This compound can penetrate blood vessels and label plasma to visualize the vascular system. It is utilized in drug delivery systems because TRITC maintains stability across a broad pH range (pH 2–11) and exhibits resistance to photobleaching.
