| 20080293144 | FIVE-PART DIFFERENTIAL WHITE BLOOD CELL CONTROL AND METHOD FOR PREPARATION OF THE SAME - The present invention provides a method for preparing a five-part differential white blood cell control and a white blood cell control prepared thereby. The white blood cell control obtained by the method of the present invention perfectly retains the light scattering properties of every type of white blood cells and has much higher stability than that of real white blood cells, and therefore can be used for the quality control of five-part differential hematology analyzers based on the principle of multi-angle light scattering. | 11-27-2008 |
| 20080293145 | SINGLE POPULATION OF SIMULATED LEUKOCYTE GRANULES, CALIBRATORS COMPRISING THE SAME AND METHODS OF PREPARING THE SAME - The present invention discloses a single population of simulated leukocyte granules prepared from mammalian whole white blood cells, which is useful in calibrators for a hematology analyzer, a calibrator comprising the single population of simulated leukocyte granules, and a method of preparing the single population of simulated leukocyte granules. The method of preparing single population of simulated leukocyte granules according to present invention comprises the steps of: obtaining mammalian whole white blood cells; treating the mammalian whole white blood cells under the action of a hemolytic agent in the presence of a leukocyte treating liquid, i.e., an isotonic saline solution comprising a fixative, a oxidizer and a carbohydrate; fixing the treated mammalian whole white blood cells with a fixative; and suspending the fixed cells in a preservation medium suitable for long-term preservation of fixed cells. | 11-27-2008 |
| 20090004747 | FILM SENSORS FOR DETECTING FREE CHLORINE - The present invention discloses a thin reagent containing film sensor for detecting and measuring free chlorine in water, where components of the film sensor are a polymeric substrate that contains reactive material, an organic polyhydroxy compound, a reagent that creates an associated polymeric matrix, and an indicator; and a method for making the same. The film sensor can be formed to fit a specific dimension or shape. The film sensor swells or dissolves when exposed to aqueous solutions so that said reagent is released so that it can react with free chlorine, or the film sensor swells when exposed to aqueous solutions so that the aqueous solution diffuses into the film sensor and reacts with said reagent contained within the swollen film sensor. | 01-01-2009 |
| 20090215181 | Multi-Analyte Reference Solutions - The present invention provides a reference solution for use in instruments that determine hematocrit levels in biological samples by measuring the resistance and/or conductivity of the biological samples. A reference solution according to the invention achieves conductivities representative of known hematocrit levels in blood, while maintaining tolerable levels of interference with the measurement of other analytes in the reference solution. | 08-27-2009 |
| 20100261279 | MASS SPECTRUM-BASED IDENTIFICATION AND QUANTITATION OF PROTEINS AND PEPTIDES - Method to quantitate peptides in a sample by mass spectroscopy wherein the improvement comprises providing internal standard peptides isobarically tagged at the N and C terminus. | 10-14-2010 |
| 20100285594 | MICROBEAD KIT AND METHOD FOR QUANTITATIVE CALIBRATION AND PERFORMANCE MONITORING OF A FLUORESCENCE INSTRUMENT - Fluorescently labeled microsphere calibration and quality control particles for use in establishing standardized fluorescence detector setup, monitoring daily QC of flow cytometers and quantitative calibration of the fluorescence detectors in traceable units of measure (molecules equivalent soluble fluorescence; MESF). | 11-11-2010 |
| 20110189777 | METHODS AND COMPOSITIONS FOR IMPROVED DIAGNOSTIC ASSAYS - The present invention describes diagnostic calibration methods and related compositions for flow cytometry instruments using synthetic control particles as an internal reference standard. The invention provides synthetic control beads which substantially reduce the drawbacks of conventional control beads. Synthetic beads coated with C3, C4 or CR1 and a non-specific spacer protein such as ovalbumin provide a control bead without the positive reactivity seen in conventional BSA controls. The present invention further provides a buffer system containing non-specific blockers and assay performance enhancers that do not interfere with analyte detection. The invention provides advantageous improvements over prior instrument calibration procedures, and provides control beads that enable consistent, reproducible data for diagnostic assays using flow cytometry. | 08-04-2011 |
