Dextran synthesis by immobilized dextran sucrase
Biochimie, 1980Dextran sucrase has been produced by fermentation of Leuconostoc mesenteroides NRRL B-512, with and without continuous sucrose addition to improve enzyme production. The enzyme preparation has been concentrated from the fermentation broth by ultrafiltration and purified by gel permeation chromatography on Ultrogel.

Dextran, a common plasma substitute, sometimes induces life-threatening hypersensitivity reactions. In this article Wolfgang Richter and Harriet Hedin discuss recent evidence that these Type III anaphylactic reactions, caused by natural antibodies, can be abolished by pretreatment o f patients with monovalent hapten dextran.

Crystallization of dextran and dextran triacetate
Polymer Science U.S.S.R., 1975Abstract It was shown that dextran produced by the strain SF-4 Leuconostoc Mesenteroides is a crystalline polymer with a glass transition temperature of 140° and flow temperature of 180° Treatment of dextran with water and formamide results in crystallization of the polysaccharide and reduces the temperature of crystallization.

DEXTRANS, a mixture of glucose polymers of various size and geometry, were introduced into medicine in the early 1950's by the Swedish scientists, after a long search for a practical nontoxic plasma substitute. 1 As a byproduct of this search, it was soon found that the high fractions of dextrans produced erythrocyte aggregation, impaired ...

The Effect of DEAE Dextran, Dextran Sulfate and Dextran on Porcine Mixed Lymphocyte Reaction
Zentralblatt für Veterinärmedizin Reihe B, 2010Summary The polycation DD moderately stimulated lymph node lymphocytes from pigs and considerably enhanced MLR. The latter effect was especially marked when the reaction was in the descending phase. The MLR was dependent on cell number, and there was a strong correlation between optimal effective DD dose and cell number.

Dextran is a complex, branched and hydrophilic polysaccharide composed of anhydroglucose rings. This chapter highlights recent progress in the synthesis of new materials based on dextran. It summarizes recent developments in the preparation of dextran derivatives with a focus on the chemical structure which make these materials, e.g.
