摘要: This invention provides compositions and methods for assaying the presence of a target analyte in a sample using a solid support. Embodiments of the present invention provide a solid support having a binding protein, such as an antibody, antibody fragment or protein receptor, immobilized to the solid support and at least two separate nucleic acid primers immobilized near the binding protein. This invention also provides a method for tethering two or more polypeptide subunits to generate a multifunctional fusion protein, which can have a primary function, e.g., binding a target analyte, such as a target protein, or an enzymatic activity, and one or more of the subunits of the fusion protein carries out a secondary function, e.g., capture on a solid matrix or quantitation.

摘要: This invention is related to the area of the capture, detection and quantitation of proteins. In particular, it relates to making and using recombinant antibodies bound to oligonucleotides and using such complexes for analytic purposes. These techniques are designed to permit multiplexed detection and quantitation of very large numbers of proteins.

摘要: To increase the efficiency of the selection of antibodies of desired specificity, we create multi-bait strain(s) in which one bait is the target and one or more bait(s) are non-target. The non-target bait(s) may use one or more DNA-binding domain(s) that differ(s) from that of the target bait and thereby activate one or more different reporters from that activated by the target bait. Library hits that activate both sets of reporters are presumed to be inadequately specific and can be eliminated from further consideration. Alternatively, a non-target bait may be replaced with a second target bait, and hits selected that activate both sets of reporters. Other combinations of elements can be used.

摘要: The present invention relates to systems and methods for sequencing nucleic acids, including sequencing nucleic acids in fluidic droplets. In one set of embodiments, the method employs sequencing by hybridization using droplets such as microfluidic droplets. In some embodiments, droplets are formed which include a target nucleic acid, a nucleic acid probe, and at least one identification element, such as a fluorescent particle. The nucleic acid probes that hybridize to the target nucleic acid are determined, in some instances, by determining the at least one identification element. The nucleic acid probes that hybridize to the target nucleic acid may be used to determine the sequence of the target nucleic acid. In certain instances, the microfluidic droplets are provided with reagents that modify the nucleic acid probe. In some cases, a droplet, such as those described above, is deformed such that the components of the droplets individually pass a target area.
