  • Protein expression system
    Patent number: 9115364
    Abstract: The present invention relates to a method of producing a target protein, which method comprises expressing said protein in a host cell which contains a nucleic acid molecule which encodes a chimeric protein, said chimeric protein comprising a signal peptide from a non-mammalian bulk-secreted protein and said target protein; nucleic acids, vectors, host cells and kits for carrying out the method are also described.
    Type: Grant

  • Fluorescent tube driver and lighting system
    Patent number: 5065074
    Abstract: The invention relates to a low voltage, high frequency driver circuit for a fluorescent tube which has high efficiency and low heat output, the invention provides a fluorescent tube driver having first positive and second nominally zero input terminals arranged to be supplied by a low voltage dc source comprising an oscillator circuit consisting of a current source effectively connected through a first capacitor to the second input, a transformer having first and second windings and a transistor, the base of the transistor being connected through the first winding to the junction of the current source and the first capacitor, the collector of the transistor being connected through the second winding to the first input and the emitter of the transistor being connected to the second input, the current source being adjustable such that the power output is in the range 18 to 40 watts, and output means comprising a third winding on the transformer, the third winding having a greater number of turns than the first
