  • Patent number: 6461860
    Abstract: An automated mechanism for guiding a microelectrode toward an oocyte placed in a perfusion chamber consists of a movable guide tube holding the electrode and a fixed guide collar in fixed relation to the target oocyte. Because the guide tube and guide collar are independently mounted, the alignment of the tip of the microelectrode is effected by its placement within the precisely aligned guide collar, irrespective of any fine misalignment of the guide tube. Accordingly, a change of microelectrode in the guide tube does not affect its final alignment toward the oocyte so long as the calibration of the guide collar is not disturbed, thereby providing a mechanism for maintaining the alignment of different microelectrodes successively mounted in the system without requiring recalibration.

  • Patent number: 6461864
    Abstract: Transgenic non-human animals one having a general deletor construct and a second having a general reporter construct are described. The general deletor animals express a heterologous recombinase under the control of an ubiquitously expressed endogenous promoter. Specifically, the Cre recombinase is inserted into the ROSA26 locus of the mouse. The general reporter animals have a gene which is desired to remove flanked by sites recognized by the is heterologous recombinase. This flanked sequence is operatively associated with a marker gene such that when the gene sequence flanked by sites recognized by the heterologous recombinase is excised, the reporter gene is expressed. When the general deletor mouse is crossed with the general reporter mouse the heterologous recombinase is expressed in essentially all cells of the resultant descendants under the control of the ubiquitous promoter. Expression of the recombinase results in the excision of the desired gene in essentially all cells of the descendant animals.

  • Patent number: 6461869
    Abstract: A gene therapy system is disclosed that selectively kills leukemia cells in bone marrow, while leaving stem cells unaffected. All cells in a mixture of stem cells and leukemia cells are transfected with a high efficiency gene transfer vector. The vector carries a eukaryotic expression construct encoding a toxin gene. This toxin gene is expressed only in leukemia cells, not in stem cells. Differential expression of the toxin gene in leukemia cells and stem cells may be achieved by placing the coding sequence under the control of an appropriate promoter, such as the RSV promoter or the SV40 promoter. High gene expression has been demonstrated in a panel of transformed leukemia cell lines, but no gene expression in transformed, CD34-selected, primary human stem cells. The treatment will be useful not only for leukemia patients, but also for other cancer patients undergoing autologous bone marrow transplants (e.g., breast or lymphoma cancers).

  • Patent number: 6461871
    Abstract: The invention relates to a method for preparing a probe, thus prepared probe, and the use of such a probe for selectively choosing sequence for nucleic acid diagnostic purposes, using preferably homogenous solutions. The invention is based upon a great number of probes having different sequences and lengths which all are complementary to different parts of the nucleic acid to be detected, which probes are synthetised on a solid matrix. The signal which they provide in non-hybridized condition is monitored, whereupon the nucleic acid to be detected is added, and the signal is monitored again. Those probes that show the most significant difference in signal are those, from a sensitivity point of view, that are the most suitable one.

  • Patent number: 6461873
    Abstract: The caffeine detector uses a paper chromatographic technique to measure the concentration of caffeine in a beverage. The device includes a well or other receptacle for containing a predetermined test volume of the beverage. A paper strip is suspended so that one end of the strip dips into the well. The strip is divided into two zones, the first zone being coated with at least one molecular imprint polymer (MIP) which absorbs substances which may interfere with quantification of caffeine. The second zone is coated with an MIP which selectively absorbs caffeine and chromogenic reagents which provide calorimetric visualization of the migration of caffeine through the second zone. The second zone bears indicia calibrating the paper strip so that the concentration of caffeine in the beverage may be determined by the height or distance which the caffeine migrates up the paper strip.

  • Patent number: 6461874
    Abstract: It has been found that casein and salts of casein are useful as replacements for, or in addition to, BSA as materials for coating solid phases, particularly magnetic particles, used in immunoassays and other binding assays for separation of the desired analyte. By using casein, immunoassays having improved stability and fewer discordant samples have been developed. Casein used at a concentration of 0.05-4.0 grams per gram of paramagnetic particle (optimally approximately 0.78-1.2 grams of casein per gram of magnetic particle) has been found to confer this benefit.
