Partially purified thrombopoiesis-stimulating activity was prepared from the plasma of thrombocytopenic rabbits using ammonium sulfate precipitation and DEAE cellulose, Sephadex, and carboxymethyl cellulose chromatography. The protein fraction precipitated by an ammonium sulfate saturation of 60%-80%, previously shown to contain thrombopoiesis-stimulating activity, was used as starting material...

Cellulolytic fungi can easily be screened within 2 d for the production of cellulolytic enzymes by staining with Congo red, or by measuring the amount of reducing sugar (glucose) produced with the dinitrosalicyclic acid reagent method. Endoglucanase activity is visible in carboxymethyl cellulose agar plates after staining with Congo red, and fixing with HCI or NaOH. This method is essentially b...

13C nuclear magnetic resonance, paramagnetic resonance, and ultraviolet spectroscopy and highresolution gel permeation chromatography were used to investigate the process of periodate oxidation of carboxymethyl cellulose and the structure and molecular weight characteristics of its oxidised forms produced under different conditions. It was shown that, in solution and in the solid state, aldehyd...

The S-carboxymethyl derivative chains of crosslinked and noncrosslinked fibrins were prepared from purified human fibrinogen. For crosslinked fibrin, fibrinogen was clotted with thrombin in the presence of calcium and purified human factor XIII. For noncrosslinked fibrin, ethylenediaminetetraacetate was substituted for factor XIII and calcium. After reduction with dithiothrcitol and alkylation ...

in this study, wasinvestigated the effect of two thickening agents, carboxymethyl cellulose (cmc) and guar on the rheological properties of set fruit yogurt. viscoelastic modulus (g' , g'), apparent viscosity and complex viscosity increased and loss factor decreased by increasing carboxymethyl cellulose and guar content up to 0.2% and 0.06% respectively. however, in the concentrations...

this study examined the influence of pre-frying treatments and oil type on the moisture outflow and oil uptake during the frying of potato strips. the pre-treatments were 6 min blanching in a 85°c a water bath containing 0.5% calcium chloride and immersion in a 1% solution of carboxymethyl cellulose; 6 min blanching in a 85°c water bath containing 0.5% calcium chloride and immersion in a 2% sol...

Cellulose fibers were converted into a valuable cellulose derivative, which is easily marketable with additional values. Alkali cellulose and carboxymethyl cellulose (CMC) is the most important cellulose derivatives. Alpha-cellulose was furnished as raw material for production of CMC, which is obtained from short cotton fibers, then purified. Alpha-cellulose is available in the international ma...

The substrate specificities of three cellulases and a beta-glucosidase purified from Thermoascus aurantiacus were examined. All three cellulases partially degraded native cellulose. Cellulase I, but not cellulase II and cellulase III, readily hydrolyzed the mixed beta-1,3; beta-1,6-polysaccharides such as carboxymethyl-pachyman, yeast glucan and laminarin. Both cellulase I and the beta-glucosid...
