摘要:
Un procédé de récupération d'un biopolymère dans une solution consiste à utiliser des sphères pouvant subir une attraction magnétique et qui ne font pas de liaison spécifique avec le polymère. Les sphères sont suspendues dans la solution. Ensuite le polymère présent dans la solution est précipité et assume une association non spécifique avec les sphères. Lorsque les sphères sont attirées magnétiquement vers le bas, le polymère est entraîné avec elles. Le polymère peut ensuite être resolubilisé et séparé des sphères.
摘要:
A method of purifying a sample that includes a desired virus includes the steps of (i) providing a packed chromatographic column having negatively charged porous particles, (ii) equilibrating the column to the conditions to which the desired virus in the sample is to elute, (iii) contacting the sample with the packed chromatographic column such that the sample volume applied to the packed chromatographic column is less than or equal to the interparticle space of the negatively charged porous particles within the packed chromatographic column, (iv) eluting the desired virus from the packed chromatographic column, where the desired virus is in a purer state and in the conditions to which the packed chromatographic column was equilibrated.

Materials and methods for use of constrained cohydration agents in the purification of biological materials such as antibodies, viruses, cells, and cellular organelles in connection with convective chromatography, fluidized bed or co-precipitation applications.
摘要:
A method of recovering a biopolymer from solution involves the use of magnetically attractable beads which do not specifically bind the polymer. The beads are suspended in the solution. Then the polymer is precipitated out of solution and becomes non-specifically associated with the beads. When the beads are magnetically drawn down, the polymer is drawn down with them. The polymer can subsequently be resolubilised and separated from the beads.
