Bovine aortic chondroitin sulphate- and dermatan sulphate-containing proteoglycans. Isolation, fractionation and chemical characterization.
1. Guanidinium chloride (4M) in the presence of proteinase inhibitors extracted 90% of bovine aorta galactosaminoglycans as proteoglycans that were subsequently purified by ion-exchange and gel chromatography. 2. Fractionation of the calcium salts of the purified proteoglycans with increasing concentration of ethanol yielded fractions PG-25 (28%), PG-35 (45%) and PG-50 (37%). 3. Fraction PG-50 ...
متن کاملIsolation and characterization of dermatan sulphate proteoglycans from bovine sclera.
1. Proteoglycans were extracted from sclera with 4 M-guanidine hydrochloride in the presence of proteinase inhibitors and purified by ion-exchange chromatography and density-gradient centrifugation. 2. The entire proteoglycan pool was characterized by compositional analyses and by specific chemical (periodate oxidation) and enzymic (chondroitinases) degradations. The glycan moieties of the mole...
متن کاملThe copolymeric structure of dermatan sulphate produced by cultured human fibroblasts. Different distribution of iduronic acid and glucuronic acid-containing units in soluble and cell-associated glycans.
The structure of dermatan [35S]sulphate-chondroitin [35S]sulphate copolymers synthesized and secreted by fibroblasts in culture was studied. 35S-labelled glycosaminoglycans were isolated from the medium, a trypsin digest of the cells and the cell residue after 72h of 35SO42-incorporation. The galactosaminoglycan component (dermatan sulphatechondroitin sulphate copolymers) was isolated and subje...
متن کاملStructure and properties of dermatan sulphate proteoglycans.
Introduction Fibrous connective tissues like sclera, skin, tendon and cornea have a high content of collagen but only small amounts of proteoglycans and structural glycoproteins. The specific blend of collagen and proteoglycan types determines the properties of the tissue. The proteoglycans are characterized by having a central protein core substituted by one or several glycosaminoglycan chains...
متن کاملDesign of Copolymeric Materials
We devise a method for designing materials that will have some desired structural characteristics. We apply it to multiblock copolymers that have two different types of monomers, A and B. We show how to determine what sequence of A’s and B’s should be synthesised in order to give a particular structure and morphology. Using this method in conjunction with the theory of microphase separation dev...
