	abstract = {The efficient amplification of genomic libraries, cDNA libraries and other complex mixts. of genes by PCR is impeded by two phenomena: firstly, short fragments tend to be amplified in preference to larger ones; and, secondly, artifactual fragments are generated by recombination between homologous regions of DNA. Recombination in this case occurs when a primer is partially extended on one template during one cycle of PCR and further extended on another template during a later cycle. Thus, chimeric mols. are generated, the short ones of which are then preferentially amplified. A variety of PCR protocols have been proposed to minimize these problems, most of which rely on high template concns. and low nos. of PCR cycles. Clearly, however, such an approach is not viable if little template DNA is available. Here we describe a protocol for amplifying complex DNA mixts., based on the compartmentalization of genes in a water-in-oil (w/o) emulsion. Template fragments are segregated in the minute aq. droplets of the emulsion and amplified by PCR in isolation. This approach alleviates the problems described above while enabling the use of small amts. of template DNA and high nos. of PCR cycles.

	abstract = {The goal of in vitro compartmentalization (IVC) is to divide a large reaction between many microscopic compartments. This technique was first developed to generate "artificial cells" for the directed evolution of proteins. Typically, an aq. soln. of genes and an in vitro transcription-translation system is stirred (or homogenized) into an oil-surfactant mixt. to create a water-in-oil (w/o) emulsion with -1010 aq. droplets per mol of emulsion. The majority of droplets contain no more that a single gene along with all of the mol. machinery needed to express that gene. The expressed proteins and the products of their catalytic activities cannot leave the droplets, and so genotype is coupled to phenotype in vitro, making it possible to select very large libraries of genes (108-1011 genes). We describe the advantages and applications of IVC. A protocol for performing a directed evolution expt. by IVC makes use of one or more w/o emulsions. This procedure involves the generation of a gene library, the performance of a selection, and the subsequent recovery of the selected genes by PCR. We also describe two procedures for converting w/o emulsions to water-in-oil-in-water (w/o/w) emulsions for high-throughput screening using a fluorescence-activated cell sorter (FACS). Finally, we describe two methods for delivering substrates, regulators and other compds. to the preformed aq. droplets of w/o emulsion. [on SciFinder(R)]},

	abstract = {The present invention provides an in vitro system for compartmentalization of large mol. libraries and provides methods for selection and isolation of mols. having desired activities from such libraries. The present invention provides novel and inventive applications of IVC for the selection of mols. being capable of modulating a particular activity of a known biol. active moiety, including, but not limited to an enzyme. The inventors of the present invention utilize a micelle delivery system that enables the transport of various solutes, including metal ions, into the emulsion droplets thereby inducing a desired activity of the known biol. active moiety or of the gene product. The present invention is based ion part on the unexpected finding that an IVC system can be used for directed evolution of nuclease inhibitors. In vitro compartmentalization (IVC) uses water-in-oil emulsions to create artificial cell-like compartments in which genes can be individually transcribed and translated. Here, the inventors present a new application of IVC for the selection of DNA-nuclease inhibitors. They developed a nano-droplets delivery system that allows the transport of various solutes, including metal ions, into the emulsion droplets. This transport mechanism was used to regulate the activity of colicin nucleases that were co-compartmentalized with the genes, so that the nucleases were activated by nickel or cobalt ions only after the potential inhibitor genes have been translated. They demonstrated its utility by selecting libraries of the gene encoding the cognate inhibitor of colicin E9 (immunity protein 9, or Im9) for inhibition of another colicin (ColE7). The in vitro evolved inhibitors show significant inhibition of ColE7 both in vitro and in vivo. These Im9 variants carry mutations into residues that det. the selectivity of the natural counterpart (Im7) while completely retaining the residues that are conserved throughout the family of immunity protein inhibitors.
