    摘要: The present invention concerns a novel means by which liquids can be moved or mixed. Microwaves strike and heat materials that are highly susceptible to microwave heating. The susceptible materials are on, within, or near materials that melt or change shape in response to temperature increases. Upon microwave irradiation, these materials change shape (e.g., shrink or melt), causing the movement of liquids. The invention is important in many microfluidics applications, especially in biomedical analysis, where it is valuable to be able to move small volumes of liquids (e.g., on a microarray chip).

    摘要: Electrochemiluminescent enzymes, their preparation and use as biosensors are disclosed. Specifically, two appendages are covalently attached to a desired dehydrogenase enzyme; (1) a nicotinamide adenine cofactor or analog thereof, and (2) a luminescent ruthenium complex. For example, glucose concentrations is the following way. A doubly-modified glucose dehydrogenase could oxidize glucose with concomitant reduction of the attached NAD+ to NADH. Because NADH, but not NAD+, is able to interact with surface ruthenium to promote ECL, only enzyme molecules that have reacted with glucose will emit light from their ruthenium label in an ECL instrument. The relative close proximity of NADH and ruthenium on the enzyme surface enhances light emission as compared to the same concentrations in free solution. When NADH reduces ruthenium, it returns to become NAD+, permitting multiple cycles of ECL light emission from a single enzyme molecule. Such biosensors can be used in solution or bound to a solid surface. Assays employing the biosensor molecules can be performed on an IGEN OrigenR Analyzer.

    摘要: Electrochemiluminescent-labels and enzyme substrates, which preferably are conjugated, are used in immunoassays and electrochemiluminescence is generated catalytically. In conventional electrochemiluminescence immunoassays, an anti-analyte antibody molecule can give rise to typically 6-8 electrochemiluminescence-active ruthenium atoms, while in the present invention, each enzyme-labeled anti-analyte molecule can give rise to thousands of electrochemiluminescence-active ruthenium atoms per second. An exemplary immunoassay is based on a catalytic process employing &bgr;-lactamase-conjugated anti-analytes which enzymatically hydrolyze electrochemiluminescent-labeled substrates, making them strongly electrochemiluminescent. The electrochemiluminescence signal generated by each anti-analyte molecule (i.e., each analyte molecule) is much greater than with the conventional method. Accordingly, greater sensitivity can be gained in the measurement of low concentrations of a given immunoassay analyte.

    摘要: Disclosed and claimed are methods for selecting a recombinant virus, phage or cell expressing a catalytic antibody or catalytic portion thereof, or for selecting catalytic activity by a moiety. The method employs reaction-based selection for catalytic activity. The method can also be used to concentrate (increase the proportion of catalytic to non-catalytic moieties) a sample containing a catalytic moiety or viruses, phages or cells expressing a catalytic moiety. The selection or concentrating can be by employing a mechanism-based inhibitor, catalysis-accelerated movement, surface binding, changes in enthalpic component of binding as a function of temperature, or changes in binding by competition, or combinations thereof. The invention also comprehends a method for producing a recombinant virus or a cell-line expressing a catalytic moiety such as a catalytic antibody or catalytic portion thereof; and, this method can include infecting a suitable host with viruses which are screened for the expression. In addition, recombinant viruses and cell-lines so expressing a catalytic moiety such as a catalytic antibody or catalytic portion thereof are also disclosed and claimed.

    摘要: A process is disclosed by which a polynucleotide is directly synthesized from the peptide or protein that it encodes without the need for sequencing (or sequence analysis) of the peptide or protein. Information contained in the sequence of the peptide or protein is directly coupled, by the process of reverse translation, to the synthesis of the polynucleotide. The usefulness of reverse translation is that it facilitates the amplification of information held in the amino acid sequence (the primary structure) of an unknown protein or peptide. Amplification is useful for, among other things, the identification and/or scientific investigation of the peptide or protein.
