This assay used DEAE dextran to stabilize polymers, which were then collected by filtration through a nylon membrane. |
The polysaccharides used were levan from Bacillus subtilis, inulin DP 10 from chicory root, and dextran. |
The viscosity of the dextran solution chosen for the go-and-stop experiment allowed testing most red cells of the population. |
After the subjects were detrained, they were infused with a dextran solution to expand their blood volume until it exceeded their trained level. |
The refractive index was chosen to reproduce dextran concentrations because dextran is hygroscopic. |
But being small makes us nimble, so we can adapt quickly when a buyer asks us to modify our basic dextran product for a new purpose. |
