    • The present invention provides a method, device and diagnostic kit for separating and/or concentrating an analyte from a mixture containing one or more contaminants according to size using a two-phase aqueous micellar system. The methods and devices are applicable to a wide range of analytes including environmental pollutants and biological materials. Conditions for optimizing size separation of analyte and contaminant are provided and include selection of a single surfactant type or surfactant mixture, surfactant concentration and composition, temperature, pH, salt type and concentration, and the addition of polymers. The separation or concentration efficiencies can be further enhanced by repeatedly generating the two-phase aqueous systems in a multi-stage operation. This invention can be used for removing viruses from proteins following fermentation processes, as well as for concentrating viruses for vaccine manufacturing or gene therapy.
    • 本发明提供了一种用于使用两相水性胶束系统根据尺寸从含有一种或多种污染物的混合物中分离和/或浓缩分析物的方法,装置和诊断试剂盒。 方法和装置适用于各种分析物,包括环境污染物和生物材料。 提供用于优化分析物和污染物的尺寸分离的条件,并且包括选择单一表面活性剂类型或表面活性剂混合物,表面活性剂浓度和组成,温度,pH,盐类型和浓度,以及加入聚合物。 通过在多级操作中重复产生两相含水体系可以进一步提高分离或浓缩效率。 本发明可用于从发酵过程中的蛋白质中除去病毒,以及用于浓缩用于疫苗制造或基因治疗的病毒。
