    摘要: An improved double balanced mixer is provided which in one embodiment includes a first balun for receiving a first single input and providing a first balanced output having two ports, a second balun for receiving a second single input and providing a second balanced output having two ports, and a balanced mixer core responsive to the first and second balanced outputs to provide a mixed signal from the first and second single inputs. The first balun includes an RC network coupled between at least one of the ports of the first balanced output and one of ground and a common mode node of the first balun to improve the linearity of the double balanced mixer.

    摘要: A method is provided for screening for agents that affect protein degradation rates, the method comprising: taking a library of cells, the cells expressing a fusion protein comprising a reporter protein and a protein encoded by a sequence from a cDNA library derived from a sample of cells, the sequence from the cDNA library varying within the cell library; contacting the library of cells with a plurality of agents which may affect protein degradation rates; for each agent, selecting cells in the library which express short-lived proteins based on whether the cells have different reporter signal intensities than other cells in the library, the difference being indicative of the selected cells expressing shorter lived fusion proteins than the fusion proteins expressed by the other cells in the library; and characterizing the fusion proteins expressed by the selected cells for each agent.

    摘要: Methods, compositions and kits are provided for sensitive and quantitative detection of nucleic acid, especially for the determination of the presence and/or amount of a target nucleic acid with mutations or single nucleotide polymorphism (SNP). In particular, assays are provided for amplifying a target nucleic acid via ligation of designed oligonucleotide probes and linear amplification by using an RNA polymerase, such as T7 polymerase. The assays can be used for diagnosis, prognosis or monitoring of diseases or disorders, for pharmacogenomic studies of patient stratification and drug responses, for discovery of therapeutic targets, or for forensic analysis.
