  • Patent number: 8610303
    Abstract: There is provided herein a system and method for generating downhole electricity from wells or similar apertures that penetrate sufficiently deep into the subsurface to allow liquid water to be converted to steam. In the preferred embodiment, a well that reaches to a point in the subsurface where the ambient temperature at depth is significantly above the boiling point of water (i.e., greater than 212° F.) will be used, said steam providing the force necessary to turn the blades of a turbine which, in turn, provides rotational force a downhole generator, thereby resulting in the generation of electricity.

  • Patent number: 5541084

  • Patent number: 5516663
    Abstract: The present invention involves methods of improving the Ligase Chain Reaction (LCR.TM.) amplification schemes by modifying at least one probe end so that the probability of the probe contributing to spurious ligation and signal development is greatly reduced. Only after specific hybridization of the modified probe with true target are the modified ends "corrected" by endonuclease IV in a target dependent fashion to allow participation of the probe in the enzymatic ligation reaction. Specific modifications include 3' phosphate blocking groups and nucleic acid overhangs containing an abasic site at the point of ligation. Further embodiments include probes modified to contain ribonucleotide moieties which, after amplification, can be cleaved by RNase to destroy the amplification products and reduce the risk of contamination.

  • Patent number: 5024941
    Abstract: A vector including a DNA sequence encoding a secretory signal sequence substantially identical to the secretory signal-encoding sequence of a glucoamylase gene from Saccharomyces diastaticus or S. cerevisiae; and upstream from the signal-encoding sequence, a DNA sequence capable of promoting transcription in yeast (e.g., a high yield promoter, such as the promoter of the triose phosphate isomerase gene), transcription of the signal-encoding sequence being under the control of the transcription-promoting sequence, a site for the insertion into the vector of a heterologous DNA sequence, in reading frame with the signal-encoding sequence. The vector is useful as an expression vector in yeast.
