    摘要: The present invention contemplates various devices that are configured to separate a sample, which contains more than one unique species, into any desired number of sub-samples by passing the sample across a like number of separation media configured for a first separation protocol. Each of the sub-samples may be further separated by an additional separation protocol, thereby creating a plurality of mini-samples, each of which may be further separated and/or analyzed. The invention also contemplates using a simple method of using conduits to form a fluid path that passes through a plurality of separation media, each of which media is configured to isolate a particular sub-sample. After various sub-samples of the sample are isolated by the various separation media, the conduits may be removed, thereby enabling each of the isolated sub-samples to be further separated and/or analyzed independent of any other sub-sample.

    摘要: Media and devices, such as anion exchangers including such media, wherein the media is a membrane having a surface coated with a polymer such as a polyallylamine. The resulting membrane offers stronger binding of protein impurities and superior removal of host cell proteins from biological samples than conventional ligands based on quaternary ammonium salts, including trimethylammonium ligands. Also described is a chromatography scheme and method for purifying monoclonal antibodies, wherein the anion exchange sorber is placed downstream of an affinity column (such as Protein A or Protein G affinity column) and optionally one or more polishing devices such as cationic exchange columns. Little or no dilution of the cation exchanger pool (or affinity column exchange pool where no cation exchanger is used) is necessary to lower the conductivity of the sample. The sorber functions well to strongly bind host cell proteins and other impurities even at high conductivities and pH.

    摘要: During the production of recombinant proteins from gram negative bacteria, lipopolysaccharides (LPS, endotoxin) are released along with the protein of interest. In many instances, LPS will copurify with the target protein due to specific or non-specific protein-ILPS interactions. We have investigated the ability of alkanediols to effect the separation of LPS from protein-LPS complexes while the complexes are immobilized on anion or cation exchange chromatographic media. Alkanediols provide a safer alternative to the use of other organics such as alcohols or acetonitrile due to their lower toxicity and decreased flammability. In addition, they are less costly than many of the detergents that have been used for such purposes. LPS removal efficiency increased with increasing alkane chain length. 1,2-alkanediols were more effective than terminal alkanediols in the separation of LPS from protein LPS complexes.
