摘要： The present invention relates to methods of isolating biomolecules. More particularly, the invention relates to methods for isolating antibodies (mAbs) and related proteins including antibody fragments (Fabs) under conditions where they are positive and relatively hydrophobic and will react with negatively charged polymer to form polymer-protein complexes which precipitate. The isolation can be accomplished using inexpensive and biocompatible negatively charged polymers such as polyacrylic acid or carboxymethyldextran polymers of various molecular weights as precipitant. It occurs at relatively high concentrations of polymer (e.g. 10%) and high salt concentration (>50 mM) and conductivity (e.g. >10 mS/cm) over wide range of pH.

摘要： The present invention relates to a process of enriching one target compound from a liquid, which process comprises at least one step of isolation performed by differentially partitioning between two aqueous phases. In the present invention the phases are formed by adding a thermally responsive, self-associating (i.e. clouding) hydrophilic polymer, and if needed some additional salts, to an aqueous biotechnical solution (such as a fermentation sample or bioseparation process stream) under thermal and other conditions where the solution separates into a one polymer, two-phase system with one phase enriched in the polymer. The target compound is to be found in the phase not enriched in the polymer, while a significant though varying percentage of contaminants may differentially partition to the phase interface or the polymer enriched phase. With minor or no modification the target containing phase solution can be further processed via standard unit operations such as precipitation, chromatography, and filtration to further purify target and remove any residual polymer.
摘要翻译：本发明涉及从液体中富集一种目标化合物的方法，该方法包括通过在两个水相之间进行差异分配而进行的至少一个分离步骤。在本发明中，通过将热响应，自缔合（即，混浊）的亲水聚合物和如果需要的话添加一些额外的盐，在热和/或热处理下，向水生物技术溶液（例如发酵样品或生物分离工艺流）溶液分离成一种聚合物的其它条件，两相体系中一相富集聚合物。目标化合物可以在不富集聚合物的相中找到，而显着的不同百分比的污染物可以差异地分配到相界面或聚合物富集相。通过微量或不改变，可以通过标准单元操作（如沉淀，色谱和过滤）进一步处理包含相溶液的溶液，以进一步纯化目标物并除去任何残留的聚合物。

摘要： There is a recognized need for novel, more simplified, approaches to isolation of plasma from whole blood, as well as a need to isolate cell-free plasma fractions containing different plasma proteins. Methods are divulged for use of aqueous phase systems, formed in blood or blood containing solutions via addition of a single polymer at relatively low concentration, to effect isolation (clarification) of plasma proteins from blood cells. Methods are also divulged to replace widely used Cohn-type plasma protein fractionation which is based on sequential addition of up to 40% (v/v) ethanol and other precipitants, with simple sequential addition of a polyacid. The latter results in isolation of plasma protein fractions (i.e. fibrinogen, immunoglobulin, albumin) in sequence similar to that obtained with Cohn Fractionation and therefore may be suitable for use to reduce solvent use and solvent-related process complications in existing plasma protein purification processes. It may also support use of polymeric film based containers in novel solvent free plasma fractionation processes. The methods disclosed may also be suitable for use in smaller scale plasma protein isolation, in research and diagnostic applications. The general methodologies are robust and can function over a broad range of process variables such as temperature and pH.
