    • Disclosed is a process for identifying clones having a specified activity of interest, which process comprises (i) generating one or more expression libraries derived from nucleic acid directly isolated from the environment; and (ii) screening said libraries utilizing an assay system. More particularly, this is a process for identifying clones having a specified activity of interest by (i) generating one or more expression libraries derived from nucleic acid directly or indirectly isolated from the environment; (ii) exposing said libraries to a particular substrate or substrates of interest; and (iii) screening said exposed libraries utilizing a fluorescence activated cell sorter to identify clones which react with the substrate or substrates. Also provided is a process for identifying clones having a specified activity of interest by (i) generating one or more expression libraries derived from nucleic acid directly or indirectly isolated from the environment; and (ii) screening said exposed libraries utilizing an assay requiring a binding event or the covalent modification of a target, and a fluorescence activated cell sorter to identify positive clones.
    • 公开了用于鉴定具有特定的感兴趣活性的克隆的方法,该方法包括(i)产生一种或多种源自从环境直接分离的核酸的表达文库; 和(ii)使用测定系统筛选所述文库。 更具体地说,这是通过(i)产生一种或多种从环境中直接或间接分离的核酸产生的表达文库来鉴定具有特定活性的克隆的方法; (ii)将所述文库暴露于感兴趣的特定底物或底物; 和(iii)使用荧光激活的细胞分选仪筛选所述暴露的文库,以鉴定与底物或底物反应的克隆。 还提供了通过(i)生成从环境直接或间接分离的核酸产生的一种或多种表达文库来鉴定具有特定活性的克隆的方法; 和(ii)使用需要结合事件或靶共价修饰的测定法和荧光激活的细胞分选器筛选所述暴露的文库以鉴定阳性克隆。
