Description: White or off-white powder, insoluble in ethanol, stable in neutral solutions, hydrolyzed under strong acid and elevated temperatures, with end groups oxidizable in alkaline solutions. Highly soluble in water. Odorless and tasteless. Solutions can be sterilized by autoclaving at 100-115°C for 30-45 minutes. Dextran is found in the mucus secreted during the growth of certain microorganisms. It is primarily composed of D-glucopyranose linked by α,1→ bonds, with branching points at 1→2, 1→3, and 1→4 linkages. Its structure varies depending on the microbial species and growth conditions.
Application: Biochemical research. Cell studies, precipitin reactions, isolation of leukocytes from whole blood. Immunological research. Permeability studies. Measurement of inert colloidal occupied volume and biological cell wall volume.
Storage: RT, shelf life 5 years
