    • A mixture of components is flowed through a binding channel region comprising a component-binding moiety, thereby binding at least a portion of a component of interest. The mixture is then flowed through a separation channel region that includes a buffer comprising a detergent, resulting in separated components. Diluent is mixed with the separated components, diluting the detergent, and the separated components are detected. The component of interest is released from the component-binding moiety and flowed through the separation channel region. Diluent is mixed with the released component of interest, diluting the detergent, and the released component of interest is detected.
    • 组分的混合物流过包含组分结合部分的结合通道区,从而结合目的组分的至少一部分。 然后将混合物流过包括包含洗涤剂的缓冲液的分离通道区域,得到分离的组分。 将稀释剂与分离的组分混合,稀释洗涤剂,并检测分离的组分。 感兴趣的组分从组分结合部分释放并流过分离通道区。 将稀释液与所释放的感兴趣组分混合,稀释洗涤剂,并检测释放的感兴趣组分。

    • This invention provides a method of recovering and purifying chymosin from fermentation used for microbial production of chymosin. The fermentation mixture is filtered to provide a filtrate containing the chymosin. The filtrate is first prepared by either adjusting it to a low pH, such as about 2 and/or adjusting the salt concentration of the filtrate to at least about 2M. The aqueous filtrate mixture is contacted with a phenyl-sepharose resin, which selectively binds the chymosin from the filtrate. The filtrate remaining after the contact with the phenyl-sepharose resin is discarded, and the phenyl-sepharose resin column is eluted with water or dilute salt solution to obtain substantially pure chymosin in a single elution step.
    • 本发明提供从用于微生物生产凝乳酶的发酵中回收和纯化凝乳酶的方法。 将发酵混合物过滤以提供含有凝乳酶的滤液。 首先通过将滤液调节至低pH(如约2)和/或将滤液的盐浓度调节至至少约2M来制备滤液。 将含水滤液混合物与苯基 - 琼脂糖树脂接触,苯基 - 琼脂糖树脂从滤液中选择性地结合凝乳酶。 在与苯基 - 琼脂糖树脂接触后残留的滤液被丢弃,苯基 - 琼脂糖树脂柱用水或稀盐溶液洗脱,以在单一洗脱步骤中获得基本上纯的凝乳酶。
