Determination of Molecular Weights of Dextrans by Means of Alkaline Copper Reagents

نویسنده

  • C. F. Snyder
چکیده

Reducing values were determined for samples of clinical dextrans, gentiobiose, and isomaltose with several alkaline copper reagents. The results for t he dextrans were converted to number-average molecular weights on the assumption th a t eq uimolecular quantities of dextran , isomaltose, and gentiobiose have approximately the same reducing power . The molecular weights, t hus obtained , are in fair agreement with values obtained by ~he recently developed radioactive cyanide method . The results show that copper-r.educmg methods are s uitable for t he determination of the number-average molecular weIg hts of clinical dextrans .

Spectrophotometric Analysis of Vardenafil in Tablet Dosage Forms by Using Electrophilic Coupling Reagents

Two new spectrophotometric methods (M1 and M2) are developed for the determination of vardenafil in bulk and in tablet dosage forms. The method M1 involves oxidative coupling of vardenafil with 3-methyl-2-benzothiazolinone hydrazone hydrochloride in presence of ferric chloride in acidic medium yielding green colored chromogen with absorption maxima at 625 nm. The method M2 is based on the oxida...

Preparation and Study of Molecular Structure of Copper Ions Doped in a Silica Xerogel Matrix

The silica xerogel is prepared using copper source; 0.02 mol of Cu(NO3)2.3H2O that has been added to 1 mol TEOS (tetraethyl orthosilicate). The Copper ions are doped to silica matrix by the sol gel method and determination of total molar ratio of components with a reported molar ratio of H2O /TEOS(R) = 6.2. In this method, the acidity the of reaction (pH) depends on the catalyst type in the hyd...

Prevention of interference by dextran with biuret-type assay of serum proteins.

In assay of serum proteins by use of the biuret reaction, dextran can cause turbidity by formation of an insoluble complex of dextran with copper and tartrate (or EDTA) in strongly alkaline solution. Whether or not the turbidity occurs depends on the tartrate concentration: turbidity is maximal at about 10 g/L, absent at 20 g/L or more, and only slight and delayed at 4 g/L. Two biuret reagents,...

Determination of somatic and excretory-secretory antigens of Fasciola hepatica and Fasciola gigantica using SDS-PAGE

Human fascioliasis due to unknown species and animal fascioliasis caused by both or one of Fasciola spp. are commonly seen in Iran. To compare electrophoretic patterns of somatic and excretory-secretory antigens of F. hepatica and F. gigantica  by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), the adult flukes were collected from infected slaughtered bovine livers. E/S a...
