The axonal transport of labeled macromolecules in retinal ganglion cells of rats was investigated from 1 to 20 days following intraocular injection of [3H]fucose and [35S]sulfate. Maximal incorporation of [3H]fucose into acid insoluble material in the retina was at 8 h, followed by a biphasic decline. Transported [3H]fucose (98% as glycoprotein) was in

Biochemistry, 1985
A boundary sedimentation methodology is described that avoids plateau dilution and simplifies the calculation of centrifugal parameters. The technique is designed for the preparative ultracentrifuge and uses a newly developed sectorial cell. It is based on previous developments of the transport method and depends on isokinetic or isovolumetric Cs2SO4 ...

AbstractWestern blotting and immunoprecipitation data indicated that lysosomal enzymes represent a subset of the sulfated macromolecules present in vegetative Dictyostelium discoideum amoebae and account for less than 2.5% of the total sulfate incorporated during vegetative growth.

Liquid–liquid equilibrium data of aqueous two-phase systems (ATPS) composed of polyethylene glycol (PEG) 8000 + sodium sulfate + water, PEG 8000 + ammonium sulfate + water, and PEG 8000 + magnesium sulfate + water at T = 298.15, 308.15, and 318.15 K and pH 2.0 were determined. The universal function activity coefficient (UNIFAC) model was correlated to

Abstract 1. 1. The synthesis of proteins, glycoproteins and sulfated macromolecules increase after hatching of the gastropod Concholepas concholepas larvae. 2. 2. Sulfate present in the sea-water, stimulates over 30-fold the sulfation of sulfated macromolecules but not the proteins. 3. 3.

[Sulfated macromolecules in connective tissue and their metabolism].
Biomedica biochimica acta, 1985Sulfated macromolecules are one of the major constituents of the extracellular matrix of connective tissue. The degree of sulfation is responsible for the physico-chemical properties of the extracellular matrix. Especially the fixed charged groups contribute to the reversible compressibility of the cartilage.

AbstractDeficient healing after endovascular aneurysm repair with a stent‐graft is thought to be related to pro‐apoptotic environment in abdominal aortic aneurysms and inertness of graft materials. We developed a bioactive coating containing chondroitin‐4‐sulfate and assessed its potential to improve cell adhesion, viability and resistance to apoptosis

Abstract The kinetics of oxidation of kappa-carrageenan polysaccharide as natural polymer by permanganate ion in aqueous perchlorate solutions at a constant ionic strength of 2.0 mol dm−3 have been investigated spectrophotometrically. The experimental observations showed that the pseudo-first-order plots were of inverted S-shape throughout the entire

AbstractThe use of equilibrium centrifugation in concentrated aqueous solutions of cesium salts, for the analysis and the separation of biological macromolecules, is restricted because nonspecific interactions may lead to the aggregation and the precipitation (salting out) of a given macrospecies, or to associations and coprecipitation between ...

In order to find potentially effective compounds that could prevent the covalent binding of the carcinogen N-hydroxy-2-acetylaminofluorene (N-OH-AAF) to rat liver macromolecules in vivo, the prevention of the covalent binding to RNA of the sulfate ester of the carcinogen N-OH-AAF by a series of thioethers was investigated in vitro.
