    摘要: A method of detecting two different target molecules through a single electrode is carried out by (a) providing a conductive oxidation-reduction reaction detection electrode; (b) contacting a sample suspected of containing a first and second target molecule to the electrode under conditions in which the first and second target molecules are deposited on the electrode, wherein the first target molecule comprises a first label and the second target molecule comprises a second label; (c) contacting to the electrode a first transition metal complex that oxidizes the first preselected label in a first oxidation-reduction reaction and a second transition metal complex that oxidizes the first and second labels in a second oxidation-reduction reaction, with the first and second oxidation-reduction reactions producing different detectable signals; (d) detecting the presence of the first target molecule by detecting the first oxidation-reduction reaction; and (e) detecting the presence of the second target molecule by detecting the second oxidation-reduction reaction. Devices for carrying out the method are also described.

    摘要: A method for manufacturing a molded structure in a press that includes the steps of positioning a preform (24) having a thickness in the lower mold (20), placing a quantity of resin adjacent the preform (24) so as to create a resin reservoir, and then selectively actuating one or more of the pressure actuators (28) to apply pressure to the resin reservoir to force at least a portion of the resin reservoir to infuse through the thickness of the preform (24). After the step of positioning, a top cover (32) may be placed upon the preform (24). The step of selectively actuating one or more of the pressure actuators (28) attached to an upper platen (60), may include a computer for controlling the pressure actuators (28).

    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).
