    摘要: The present disclosure relates to a differential signaling circuit including differential signaling circuitry having at least one output and one input, that can operate in multiple mode of operations while using a single, low voltage supply source. Two or more switches are included and configured to selectively couple a supply voltage to the output dependent on a mode of operation of the differential signaling circuitry. The circuit also includes a switch control biasing circuit operatively coupled to at least one of the switches and to the output of the differential signaling circuitry. The switch control biasing circuit provides a switch control biasing voltage to control a state of the switch based on a voltage level of the output. Further, a bulk biasing circuit is included and operatively coupled to the switch. The bulk biasing circuit selectively provides a bulk biasing voltage to the switch based on the voltage level of the output.

    摘要: Seamless steel tubes suitable for use as grades of casing and line pipe having yield strengths in excess of 70,000 psi, without being heat treated, are made of an alloy comprising, by weight, about 0.10% to 0.18% carbon, about 1.0% to 2.0% manganese, about 0.10% to 0.16% vanadium, about 0.008% to 0.012% titanium and about 150 parts per million to 220 parts per million nitrogen, the balance comprising iron and incidental impurities. Strains are applied to the shell in a stretch reducing mill below the T.sub.nr of the steel and above the A.sub.r3 to provoke dynamic recrystallization. The nitrogen and vanadium are preferably introduced to the steel during alloying in the form of a VN alloying agent. The vanadium, titanium and nitrogen are predominantly present as vanadium nitride and titanium nitride. The steel may also comprise 0.03% to 0.05% aluminum by weight.

    摘要: Unsymmetrical cyanine dyes that incorporate an aza-benzazolium ring moiety are described, including cyanine dyes substituted by a cationic side chain, monomeric and dimeric cyanine dyes, chemically reactive cyanine dyes, and conjugates of cyanine dyes. The subject dyes are virtually non-fluorescent when diluted in aqueous solution, but exhibit bright fluorescence when associated with nucleic acid polymers such as DNA or RNA, or when associated with detergent-complexed proteins. A variety of applications are described for detection and quantitation of nucleic acids and detergent-complexed proteins in a variety of samples, including solutions, electrophoretic gels, cells, and microorganisms.

    摘要: Embodiments of the present invention provide methods and nucleic acid reporter molecules for the detection of nucleic acid in a sample. The nucleic acid reporter molecule comprises two unsymmetrical cyanine monomer moieties, which may be the same or different, that are covalently attached by a linker comprising at least one aromatic, heteroaromatic, cyclic or heterocyclic moiety comprising 3-20 non-hydrogen atoms selected from the group consisting of O, N, S, P and C. The linker may be rigid, relatively flexible or some degree thereof. The unsymmetrical cyanine monomer moieties comprise a substituted or unsubstituted benzazolium moiety and a substituted or unsubstituted pyridinium or quinolinium moiety that is connected by a methine bridge that is monomethine, trimethine or pentamethine. The linkers form the cyanine dimer compounds by attaching to the pyridinium or quinolinium moiety of the monomer moieties. The present nucleic acid reporter molecules find utility in forming a nucleic acid-reporter molecule complex and detecting the nucleic acid. In particular, present nucleic acid reporter molecules with a rigid linker and monomer moieties with a monomethine bridge find utility in detecting RNA in the presence of DNA.

    摘要: The present invention provides methods for determining the presence of immobilized nucleic acid employing unsymmetrical cyanine dyes that are derivatives of thiazole orange, a staining solution and select fluorogenic compounds that are characterized as being essentially non-genotoxic. The methods comprise immobilizing nucleic acid, single or double stranded DNA, RNA or a combination thereof, on a solid or semi solid support, contacting the immobilized nucleic acid with an unsymmetrical cyanine dye compound and then illuminating the immobilized nucleic acid with an appropriate wavelength whereby the presence of the nucleic acid is determined. The cyanine dye compounds are typically present in an aqueous staining solution comprising the dye compound and a tris acetate or tris borate buffer wherein the solution facilitates the contact of the dye compound and the immobilized nucleic acid. Typically the solid or semi-solid support is selected from the group consisting of a polymeric gel, a membrane, an array, a glass bead, a glass slide, and a polymeric microparticle. Preferably, the polymeric gel is agarose or polyacrylamide. The methods employing the non-genotoxic compounds represent an improvement over commonly used methods employing ethidium bromide wherein the present methods retain the advantages of ethidium bromide, ease of use and low cost, but without the disadvantageous, known mutagen requiring special handling and waste procedures.
