  • Publication number: 20220333060
    Abstract: A process for purifying a composition comprising water, a target substance, impurities and optionally cells, the process comprising the steps (A) and (B): (A) preparing a liquid feedstock by performing step (Ai) and/or (Aii) on the composition: (Ai) removing at least some of the cells from the composition; (Aii) concentrating the composition by removing water therefrom; and (B) passing the liquid feedstock through an apparatus comprising at least two processing units, each such unit producing a product stream containing purified target substance and optionally a waste stream comprising at least some of the impurities, wherein each unit comprises specified components (i) to (v). The units may be essentially the same except for a device they contain, leading to advantages in terms of simplicity, cost and ease of operation, lower risk of operator error, easier maintenance and lower inventory of spare parts.

  • Publication number: 20220325231
    Abstract: Apparatus for purifying a liquid comprising a target substance comprising at least two units arranged in series such that the feed stream of the second and any subsequent units comprises the product stream from a downstream unit, wherein each unit comprises specified components (i) to (vi), including a a switchable bypass assembly. Also claimed are the units and a flowpath assembly. The units may be essentially the same except for a device they contain, leading to advantages in terms of simplicity, cost and ease of operation, lower risk of operator error, easier maintenance and lower inventory of spare parts.

  • Publication number: 20220275024
    Abstract: A process for purifying a liquid feedstock comprising a monoclonal antibody and impurities, the process comprising passing the liquid feedstock through an apparatus comprising at least two processing units, each such unit producing a product stream containing purified monoclonal antibody and optionally a waste stream comprising at least some of the impurities, wherein each unit comprises specified components (i) to (v) which include a multiple inlet flow-controller comprising two or more variable flow inlet valves for in situ production of a bioprocessing liquid by combining at least two liquids in a desired ratio. One of the units performs chromatography and another performs viral inactivation. The units may be essentially the same except for a device they contain, leading to advantages in terms of simplicity, cost and ease of operation, lower risk of operator error, easier maintenance and lower inventory of spare parts.

  • Patent number: 8461302
    Abstract: The present invention provides improved methods for the purification of factor XIII. In particular, the methods provide compositions containing 5% or less contaminating proteins. In particular embodiments of the present invention the methods provide purified factor XIII compositions comprising less than 1% activated factor XIII, less than 2% protein aggregates, and/or less than 5% charge isomers of factor XIII. The methods do not require the use a precipitation or crystallization step common to prior methods of isolating factor XIII. Instead, the method uses immobilized metal affinity chromatography to remove various contaminants common to recombinant expression of factor XIII. Further, a combination of various chromatography methods including ion exchange chromatography, hydrophobic affinity chromatography, and immobilized metal affinity chromatography comprise a simple and less expensive method to produce a pharmaceutical grade factor XIII product at high yield.

  • Publication number: 20090325229
    Abstract: This invention relates to methods for use in industrial production of recombinant globular Adiponectin (gAdiponectin). Specifically, the present invention provides a purification process suitable for production of high amounts of pure gAdiponectin. gAdiponectin is expressed in E. coli, and a purification method with which about 30 grams of gAdiponectin could be obtained from 100 liters of cell culture has been set up.
