Dextran from Leuconostoc spp. is a high-molecular-weight polysaccharide (Mr 450,000–650,000) widely used in biomedical research as a plasma volume expander, molecular sieve, and viscosity modifier. It is also applied in pharmaceutical formulations and as a standard in gel permeation chromatography. This product has a repeating glucose unit (molecular formula [C6H10O5]n, repeating unit mass approximately 162.14; the listed molecular weight of 504.4 corresponds to a trisaccharide, C18H32O16, not the repeating unit), requires no hazardous storage (ambient conditions), and carries no safety signal word. Molekula supplies Dextran from Leuconostoc spp. from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
