Studies on the enzymatic systhesis of dextran from sucrose.
The syntheses of dextrans (l-5) and levans (6-10) from sucrose by enzymes from certain bacteria and the syntheses of glycogens and starches from glucose-l-phosphate by phosphorylases from yeast (11) and animal (12-15) and plant (16, 17) tissues have a fundamental point of similarity in that, with all of them, the substrate contains the basic unit of the final polymer product in the form of a gl...
متن کاملIntravenous iron-dextran: studies on unsaturated iron-binding capacity.
A method is described for measuring the plasma unsaturated iron-binding capacity in the presence of very high concentrations of iron as iron-dextran. The procedure utilizes (59)Fe to label the apotransferrin with subsequent separation of ionic iron from transferrin-bound iron on an ion exchange or Sephadex G.25 column. The unsaturated iron-binding capacity has been measured in rabbits and dogs ...
متن کاملDextran Fractional Clearance Studies in Acute Dengue Infection
BACKGROUND Although increased capillary permeability is the major clinical feature associated with severe dengue infections the mechanisms underlying this phenomenon remain unclear. Dextran clearance methodology has been used to investigate the molecular sieving properties of the microvasculature in clinical situations associated with altered permeability, including during pregnancy and in vari...
متن کاملStudies on the fibrinogen, dextran and phytohemagglutinin methods of isolating leukocytes.
By WILLIAM A. SKOOG AND WILLIAM S. BECK T HE INCREASING INTEREST in leukocyte biochemistry and physiology is largely attributable to the invention of satisfactory simple procedures for the isolation of leukocytes from whole blood. Although some of these methods involve selective destruction of the red cells, the most useful procedures seem to be those based upon the differences in sedimentation...
متن کاملForty-first Conference Preliminary Studies on the Enzymic "removal" of Dextran from Deteriorated Cane Juice
Dextran is one of the by-products of sour-storage rot of sugar cane (Egan, 1971). The presence of dextran in cane juice entering the mill has many deleterious effects on raw sugar processing and quality (Foster, 1969a,b; Henderson, 1971; Foster and Wright, 1969; Leonard and Richards, 1969). Hence, the removal of the polysaccharide from juice may alleviate these effects. Physico-chemical methods...
