  • Patent number: 6713308
    Abstract: The analytical process utilized in the system of this invention comprises three (3) step distinct steps wherein an analyte of interest in a test sample is initially labeled and subsequently isolated within a porous medium of a test device. Once isolated within the medium, the label is displaced from the analyte, or from the complex with the analyte, and converted, under electrolytic condition, to a metallic species which is caused test to deposit upon a working electrode of the test device. This working electrode is part of an electrode array that is positioned coincident with the porous medium, yet maintained physically remote therefrom. This deposit is then stripped from the working electrode, under anodic stripping conditions, and the current generated within the electrode array monitored. The characteristic response curve that is produced thereby can be correlated with the identity and concentration of the analyte(s) with the test sample.

    Abstract: The gene of human acidic fibroblast growth factor 155 (haFGF 155) has been obtained by chemical synthesis. The nucleotide sequence of haFGF 155 gene has been deduced on the basis of haFGF 155 amino acid sequence as described in the literature. The amino acid sequence of the synthesized haFGF 155 does not differ from those described in the literature. The nucleotide sequence of haFGF gene differs from those described previously. For chemical synthesis of haFGF 155 gene, codons were used which are the ones most often used by E. coli in highly expressed E. coli proteins. A plasmid with haPGF 155 (phaFGF 155) gene was obtained and was used to transform E. coli. Production of haFGF 154 protein was achieved by cultivation of the producer strain under conditions which slow down the lytic development of lambda phage. The haFGF 154 protein accumulated in culture medium in a soluble condition as a result of the producer strain cells lysis by the lambda phage.

  • Patent number: 6284453
    Abstract: This invention is a method for controlling growth rate and metabolic state in fed-batch fermentations. Growth rate refers to the rate of exponential growth. Metabolic state refers to the relative consumption rates of the carbon and nitrogen sources. The method is based on a new use of the pH control reagent addition rate (RAR) and thus requires pH control and measurement of the RAR. The method also requires measurement of the oxygen uptake rate (OUR), or measurement of the biomass concentration (X) along with the reactor volume (V), or all three. Either the preferred embodiment or the first additional embodiment can be used when one metabolite limits growth and the metabolic state is determined by the organism through the growth rate. In the preferred embodiment, the controller feeds the growth-limiting metabolite such that the reagent-oxygen metabolic quotient, defined as RAR/OUR, is maintained at a set point corresponding to the desired growth rate.

  • Patent number: 6280618
    Abstract: Heterogeneous assays for different analytes in a single biological sample are performed simultaneously in a multiplexed assay that combines flow cytometry with the use of magnetic particles as the solid phase and yields an individual result for each analyte. The particles are distinguishable from each other by characteristics that permit them to be differentiated into groups, each group carrying an assay reagent bonded to the particle surface that is distinct from the assay reagents of particles in other groups. The magnetic particles facilitate separation of the solid and liquid phases, permitting the assays to be performed by automated equipment. Assays are also disclosed for the simultaneous detection of antibodies of different classes and a common antigen specificity or of a common class and different antigen specificities.

  • Patent number: 6267925
    Abstract: A system dynamically adjusts the delivery rate of a cryopreservation solution to red blood cells to permit freezing. The delivery rate is preferably determined according to an equation that maintains a linear change of red blood cell osmolarity over time so as to prevent osmolarity shock of the red blood cells. In the preferred embodiment, the system includes a controller that is preconfigured to automatically deliver the cryopreservation solution to the red blood cells in accordance with the equation. The system may also support the recovery of thawed red blood cells by diluting the red blood cells and washing them of the cryopreservative. Again, the system preferably adjusts the delivery rate of a dilution solution so as to prevent osmolarity shock of the red blood cells during the recovery phase. The recovered red blood cells may be suspended in a preservation solution to further increase their shelf-life following the recovery phase.

  • Patent number: 6242190
    Abstract: The present invention provides a method of rapidly screening ligands on the basis of their binding affinity and binding enthalpy by carrying out binding assays at a minimum of two temperatures. This technique permits the selection for further optimization of lead ligands that bind to the target molecules with favorable enthalpies. Those ligands will exhibit higher solubilities in aqueous solution than ligands selected by conventional means, and may exhibit lower susceptibilities to resistant mutations. The method may be utilized as a standalone technique, or may be adapted to, for example, known high throughput screening technologies. The present invention further comprises an apparatus for carrying out the described methods.
