Abstract:
Herein is reported a method for the purification of an antibody directly captured from clarified cell culture supernatants using Streamline CST and/or Capto MMC, wherein especially product related (aggregates and fragments) and process related impurities (host cell protein, media components) could efficiently be removed, resulting in a preparation with a purity comparable to classical protein A affinity chromatography.
Abstract:
Herein is reported a method for producing a polypeptide in monomeric form comprising the following step: recovering the polypeptide in monomeric form from an ion exchange chromatography material by applying a solution comprising a non-ionic polymer and an additive.
Abstract:
The present invention provides a novel adsorbent composition for recovering biomolecules from a fluid. The composition comprises positively and negatively charged microparticles in the form of ground particles. The adsorbent is particularly useful for purification of biomolecules from the cell culture.
Abstract:
The present invention relates to a method of purifying an antibody with high purity and high quality by removing impurities by sequential use of a cation-exchange column, a culture supernatant multilayer filter and an anion-exchange column without using a protein-A column that is an affinity chromatography column which is generally used for antibody purification.
Abstract:
The invention provides a method for producing a host cell protein—(HCP) reduced antibody preparation from a mixture comprising an antibody and at least one HCP, comprising an ion exchange separation step wherein the mixture is subjected to a first ion exchange material, such that the HCP-reduced antibody preparation is obtained.
Abstract:
The present invention relates to a process for the purification of an antibody fragment from a periplasmic cell extract comprising a first cation exchange chromatography step and a second anion exchange chromatography step.
Abstract:
An assembly capable of capturing and purifying expressed biological products during or at the end of a bioreaction cycle is disclosed wherein a binding resin is kept separated from the contents of the bioreactor allowing capturing, harvesting and purification of biological products in a bioreactor; the invention additionally provides means of removing undesirable metabolic products as well as provides for efficient loading of chromatography columns.
