    • A process for screening an expression library to identify clones expressing enzymes having a desired activity is provided. The process involves first generating from genomic DNA samples of one or more microorganisms an expression library comprising a plurality of recombinant cell clones, and then introducing into capillaries in a capillary array a substrate and at least a subset of the clones, either individually or as a mixture. Interaction of the substrate and a clone expressing an enzyme having the desired activity produces an optically detectable signal, which can then be spatially detected to identify capillaries containing clones producing such a signal. The signal-producing clones can then be recovered from the identified capillaries.
    • 提供了筛选表达文库以鉴定表达具有所需活性的酶的克隆的方法。 该方法包括首先从一种或多种微生物的基因组DNA样品产生包含多个重组细胞克隆的表达文库,然后将毛细管阵列中的毛细管阵列引入基质和克隆的至少一个子集,单独地或作为 混合物。 底物和表达具有所需活性的酶的克隆的相互作用产生光学上可检测的信号,然后可以在空间上检测,以鉴定含有产生这种信号的克隆的毛细血管。 然后可以从识别的毛细血管中回收信号产生克隆。

    • 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 a fluorescence activated cell sorter to identify said clones. 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 co-encapsulation, a binding event or the covalent modification of a target, and a fluorescence activated cell sorter to identify positive clones.
