Biological Activity

Dextran (Mw 70000) has an inhibitory effect on platelet aggregation and coagulation factors, and can replace part of the whole blood during blood transfusion, and is often used as a plasma volume expander (plasma replacement).

Chemical Information
Molecular Weight 70000
Formula C17H32O10
CAS Number 9004-54-0
Solubility (25°C) Water 50 mg/mL
Storage 2-8°C, dry, sealed
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
