Abstract: A method for identifying cognate pairs of a ligand species and a receptor species includes co-compartmentalizing ligand species and receptor species, forming a set of microreactors, each microreactor including a ligand species and preferably a receptor species; assaying the recognition between ligands and receptors in each microreactor and based on this assay, classifying each microreactor as positive when a ligand species and receptor species in the microreactor recognize one with the other or negative when no ligand species and no receptor species recognize in the microreactor; identifying ligand species and receptor species contained in each positive microreactor; establishing a subset of positive microreactors containing the same receptor species; determining the probability that the ligand species recognizing the receptor species corresponds to the most frequent co-compartmentalized ligand species.

Abstract: Approaches for managing communication between a first database server and a second database server are described. According to one example, an out-of-sequence data (OOSD) notification is generated by the first database server each time out-of-sequence data is received from at least one data source. The OOSD notification indicates receipt of the out-of-sequence data from the at least one data source and may include the out-of-sequence data. The OOSD notification is then transmitted by the first database server to the second database server over a dedicated communication channel. The OOSD notification is received and processed by the second database server for incorporating the out-of-sequence data within a database of the second database server in a chronological order.

Abstract: Systems, methods, and compositions relating to pretreatment and enzymatic degradation of polymeric materials comprising one or more crystallizable polymers or copolymers are generally described. Certain aspects are directed to methods comprising reacting a polymeric material comprising a crystallizable polymer or copolymer with a reactive agent to produce a pretreated polymeric material and exposing the pretreated polymeric material to a polymer-degrading enzyme. In some embodiments, the reactive agent induces chain extension, branching, and/or cross-linking of the crystallizable polymer or copolymer. In some embodiments, the reactive agent induces chain scissions followed by chain extension, branching, and/or cross-linking of the crystallizable polymer or copolymer.
