    Abstract: Systems and methods are provided for producing a protein of interest that is typically not amenable to expression in soluble form in in vitro expression systems. In some aspects, the invention provides methods of synthesizing proteins using in vitro protein synthesis systems that include a scaffold protein such as apolipoprotein or an amphipathic alpha helix containing (“AAHC”) protein, in which higher yields of soluble protein are produced than in the absence of the scaffold protein. The scaffold proteins may be provided in an in vitro protein synthesis system associated with lipid or not associated with lipid. The scaffold protein may be provided as a protein per se or may be encoded by a nucleic acid template and co-expressed with the protein of interest. The invention also provides compositions and kits for synthesis of proteins in soluble form, in which the compositions and kits include cell extracts for protein expression and isolation.

    Abstract: The present invention provides ligand-detection reagents, ligand analogs and methods for determining the presence of a ligand in a sample. The ligand-detection reagent comprises a ligand-binding antibody and a ligand analog to form an antibody-ligand analog complex wherein the ligand analog is covalently bonded to a reporter molecule. This complex may additionally comprise a labeling protein non-covalently bonded to the antibody to form a ternary complex wherein the labeling protein comprises a monovalent antibody fragment or a non-antibody protein that is covalently bonded to a label moiety. The reporter molecule is either quenched by the ligand-binding antibody or by the label moiety of the labeling protein, depending on the reporter molecule and the ligand-binding antibody, wherein the amount of quenching is directly related to the amount of ligand present in the sample. Alternatively, the ligand analog is fluorogenic wherein the ligand analog is essentially non-fluorescent in solution but when bound by the ligand-binding antibody the detectable signal increases. In this instance a decrease in signal, as opposed to the relieving of quenching, is measured for the presence of a target ligand.

    Abstract: Provided are labeling reagents and methods for labeling primary antibodies and for detecting a target in a sample using an immuno-labeled complex that comprises a target-binding antibody and one or more labeling reagents. The labeling reagents comprise monovalent antibody fragments or non-antibody monomeric proteins whereby the labeling proteins have affinity for a specific region of the target-binding antibody and are covalently attached to a label. Discrete subsets of labeling reagent and immune-labeled complexes are provided that facilitate the simultaneous detection of multiple targets in a sample-complexes are distinguished by i) a ratio of label to labeling reagent, or ii) a physical property of said label, or iii) a ratio of labeling reagent to said target-binding antibody, or iv) by said target-binding antibody. This is particularly useful for fluorophore labels that can be attached to labeling reagents and subsequently immuno-labeled complexes in ratios for the detection of multiple targets.

    Abstract: Provided herein are systems and methods for nucleotide incorporation reactions. The systems comprise polymerases having altered nucleotide incorporation kinetics and are linked to an energy transfer donor moiety, and nucleotide molecules linked with at least one energy transfer acceptor moiety. The donor and acceptor moieties undergo energy transfer when the polymerase and nucleotide are proximal to each other during nucleotide binding and/or nucleotide incorporation. As the donor and acceptor moieties undergo energy transfer, they generate an energy transfer signal which can be associated with nucleotide binding or incorporation. Detecting a time sequence of the generated signals, or the change in the signals, can be used to determine the order of the incorporated nucleotides, and can therefore be used to deduce the sequence of the target molecule.
