Micro-scale isolation of sulfated glycopeptide from tissue was achieved by successive application of pronase digestion (Step 1), cetylpyridinium chloride-fractionation (Step 2), crude heparinase digestion or chondroitinase ABC digestion plus nitrous acid treatment (Step 3) and preparative cellulose acetate membrane-electrophoresis (Step 4). By this method, sulfated glycopeptide was obtained in ...
Raw extract in 2 m CaCl2 of bovine nasal septum cartilage was eluted from 4 per cent agarose gel to give a "void volume" Fraction v-4, which was indistinguishable in composition and behavior on viscometric and sedimentation analysis from the densest fraction obtained by associative centrifugation in a cesium chloride density gradient. The sulfated proteoglycan was precipitated (Fraction A) by c...
In the synthesis of the disordered lyotropic liquid crystalline L3 sponge phase prepared with the cosurfactants cetylpyridinium chloride and hexanol, aqueous NaCl solution is used as the solvent. When this sponge phase is used as the template for L3 silica-phase processing, we replace NaCl with HCl to facilitate the acid catalysis of tetramethoxysilane in forming a templated silica gel, assumin...
