摘要:
Described herein are methods of identifying a transmembrane receptor (TMR) agonist and compounds identified by this method. The TMR agonist (TMRA) is capable of activating TMR signaling while exhibiting reduced TMR internalization over a control compound.
摘要:
A method of detecting binding interactions and target molecules, such as proteins, protein fragments, recombinant proteins, recombinant protein fragments, extracellular matrix proteins, ligands, carbohydrates, steroids, hormones, drugs, drug candidates, immunoglobulins and receptors of eukaryotic, prokaryotic or viral origin, by mediated electrochemistry using labels that react with transition metal mediator complexes in a detectable catalytic redox reaction. These labels are attached directly to binders, target molecules, surrogate target molecules, or to affinity ligands capable of binding to the target or to surrogate target molecules capable of competing with the target for binding to another binder. The labels can be naturally present (endogenous) in the binder, target or affinity ligand, or constructed by the covalent attachment of the label to the binder, target, affinity ligand or surrogate target (exogenous).
摘要:
A method of conducting a droplet-based enzymatic assay is provided. The method generally makes use of a droplet actuator. A droplet comprising an enzyme of interest is provided on the droplet actuator along with a droplet comprising a substrate which is potentially modified in the presence of the enzyme. The method involves executing droplet operations on the droplet actuator to combine the droplets, thereby yielding an assay droplet, and detecting modification of the substrate by the enzyme in the assay droplet on the droplet actuator. The enzyme of interest may, for example, be a potentially mutated or improperly folded enzyme exhibiting altered enzyme activity as compared to a corresponding normal enzyme.
摘要:
An electrode for detecting interactions between members of a binding pair, which electrode has been modified by formation of a non-conductive self-assembled monolayer, and a method of detecting biomolecules, such as nucleic acids or other targets, including receptors, ligands, antigens or antibodies, utilizing such an electrode. When contacted with a target nucleic acid, an oligonucleotide probe coupled to the self-assembled monolayer reacts with the target nucleic acid form a hybridized nucleic acid on the modified electrode surface. The hybridized nucleic acid is reacted with a transition metal complex capable of oxidizing a preselected base in the hybridized nucleic acid in an oxidation-reduction reaction, the oxidation-reduction reaction is detected, and the presence or absence of the nucleic acid is determined from the detected oxidation-reduction reaction.
摘要:
The systems and methods of the invention provide a guided approach to pyrosequencing (i.e., hybrid pyrosequencing). A de novo nucleic acid sequence may compared to a library of possible results and the next nucleotide to be dispensed is selected based on the comparison of the de novo sequence and the library of possible results. In another example, at least the first nucleotide to be dispensed is selected based on a query of a database(s) of non-sequence parameters (e.g., incidence of infection, diagnostic symptoms, sample source) and subsequent dispensations determined based on a comparison of the de novo sequence and the library of possible results (e.g., candidate sequences). The systems and methods of the invention may be performed using a droplet actuator.
摘要:
The present invention relates to providing improved hydrogen peroxide assays, as well as droplet actuators for conducting such assays. The droplet actuators of the invention may be used to conduct droplet-based hydrogen peroxide assays. They may also be associated with detectors for analyzing the results of the hydrogen peroxide assays of the invention. They may be provided as components of systems which control droplet operations and/or detection for conducting the hydrogen peroxide assays. Measurement by the detector may be used to quantify the presence of an analyte in a sample.
