A convenient method for preparative peptide separation
Analytical Biochemistry, 1972Abstract A chromatographic system has been developed for the separation of peptides on a preparative scale. The principle of the method is to use the peptide bond absorbance in the 200–250 nm wavelength range as the basis for the peptide detection, and therefore to use only inorganic buffers that are transparent at these low wavelengths ...

Separation methods for glycoprotein analysis and preparation
Journal of Chromatography B: Biomedical Sciences and Applications, 1997Several chromatographic methods have been developed for the isolation and characterization of glycoproteins. In these methods, affinity chromatography, a single-step method, or combined use with general chromatographic methods have now become essential for the purification of many biologically important glycoproteins, including alpha1-acid glycoprotein,

Study on preparation and separation of Konjac oligosaccharides
Carbohydrate Polymers, 2013To study the preparation and separation of Konjac oligosaccharides, Konjac Glucomannan was degraded by the combination of γ-irradiation and β-mannanase, and then the degradation product was separated by ultrafiltration. To our interest, for most of Konjac oligosaccharides obtained by this method, the molecular mass was lower than 2200 Da.

Preparation and separation of complexes prepared by template polymerization
Macromolecules, 1990La polymerisation de l'acide acrylique amorcee par K 2 S 2 O 8 sur une matrice de poly(vinylpyrrolidone) en milieu aqueux donne un complexe des 2 polymeres interagissant par liaisons hydrogenes. La separation des 2 polymeres se fait avec complexe greffe.

Preparative separation of tetrahydrofurfurylamine enantiomers
Russian Journal of Organic Chemistry, 2007Tetrahydrofurfurylamine enantiomers were separated on a preparative scale by fractional crystallization of diastereoisomeric salts with natural L-tartaric acid. (R)-Tetrahydrofurfurylamine was isolated in 68% yield with an optical purity of more than 98.5% according to the HPLC data.

Preparative Electrophoretic Separation of Antibody Forming Cells
Preparative Biochemistry, 1972Abstract A procedure is described for preparative electrophoretic separation of lymphoid cells. The separations were performed with a free flow electrophoretic cell separator model VAP IV (Desaga, Heidelberg, Bender & Hobein, Munich, Brinkmann Instruments, Westbury, N. Y.).

Borosilicate nanoparticles prepared by exothermic phase separation
Nature Nanotechnology, 2008Nanoparticles play an important role in chemical and biological sciences due to their ability to bind and concentrate many molecules on their surface. Polymers and silica are widely used to make nanoparticles, but efforts to make nanoparticles from borosilicate glass--which exhibits high tolerance to chemicals and solvents, combined with excellent ...
