  • Patent number: 5957895
    Abstract: A device for delivering a liquid theraputic preparation into the body of a patient by injection into or through the skin of the patient comprises a low-profile housing having a bottom surface adapted to be brought into contact with the skin of the patient. A reservoir is disposed within the housing for containing a liquid theraputic preparation to be administered. An injection needle is disposed generally horizontally in the housing, and is adapted to communicate with the reservoir. The injection needle has a bent injection end which is adapted to project through a needle aperture in the bottom surface of the housing. A movable needle carrier is disposed in the housing for carrying the injection needle and for causing the injection end of the needle to project through the needle aperture upon movement of the needle carrier.

  • Patent number: 5928869
    Abstract: A detector oligonucleotide having a sequence which forms an intramolecularly base-paired secondary structure is described for use in detecting nucleic acid target sequences and target sequence amplification. The detector oligonucleotide is further modified by linkage to two dyes which form a donor/acceptor dye pair. The two dyes are positioned on the detector oligonucleotide such that they are in close spatial proximity in the base-paired, folded secondary structure, thereby causing quenching of donor fluorescence. The detector oligonucleotide may optionally further comprise a restriction endonuclease recognition site (RERS) which remains partially or entirely single-stranded in the base-paired secondary structure. The RERS is flanked by the two dyes. In the presence of target, the base-paired secondary structure is unfolded or linearized, increasing the distance between the donor and acceptor dyes and causing a change in fluorescence of the donor and/or the acceptor.

  • Patent number: 5856145
    Abstract: A process for lysing Mycobacteria to liberate nucleic acids such as DNA and RNA comprises heating the Mycobacteria in an aqueous solution to lyse the Mycobacteria and release the nucleic acids, with the aqueous solution containing a chelating agent such as EDTA or EGTA in an amount effective to inhibit degradation of the released nucleic acids. Examples of Mycobacteria which can be lysed include Mycobacterium fortuitum and Mycobacterium tuberculosis. After lysis, the nucleic acid is preferably then amplified and detected. Kits useful for carrying out the present invention are also disclosed.
