  • Publication number: 20140315283
    Abstract: A sample cartridge (40) for microscopic imaging of a biological sample comprises a body having an end portion (43) and a pair of generally parallel opposing side edge portions (44), a locking edge portion (45) formed on the body; a carrier removably connected to or permanently connected to the body; and at least one anti-analyte antibody coupled to either the carrier or to the chamber (41) side wall portion (e.g., at the surface to be imaged, or supporting the sample to be imaged). An XYZ stage (101) for receiving such a cartridge (40) is also described.

  • Publication number: 20140186859
    Abstract: A method of automatically focusing a microscope on a specimen is carried out by capturing an image from each of a plurality of focal planes in or on said specimen, calculating a focus score for each of said images, selecting the focal plane corresponding to the image having the best focus score, and then repositioning said specimen relative to said microscope so that said microscope is focused on said selected focal plane, the method includes a plurality of exogenous targets in or on said specimen, which aids in focusing in the event particular objects of interest, such as cells/pathogens that may or may not be in the sample, are not present, or are present in low numbers. Automated microscopes and microscope cartridges useful in such methods are also described, along with methods of detecting pathogens in biological samples.

  • Publication number: 20060292624
    Abstract: A method of detecting two different target molecules through a single electrode is carried out by (a) providing a conductive oxidation-reduction reaction detection electrode; (b) contacting a sample suspected of containing a first and second target molecule to the electrode under conditions in which the first and second target molecules are deposited on the electrode, wherein the first target molecule comprises a first label and the second target molecule comprises a second label; (c) contacting to the electrode a first transition metal complex that oxidizes the first preselected label in a first oxidation-reduction reaction and a second transition metal complex that oxidizes the first and second labels in a second oxidation-reduction reaction, with the first and second oxidation-reduction reactions producing different detectable signals; (d) detecting the presence of the first target molecule by detecting the first oxidation-reduction reaction; and(e) detecting the presence of the second target molecule by d

  • Publication number: 20060029956
    Abstract: Methods and compositions for identifying ovarian cancer in a patient sample are provided. The methods of the invention comprise detecting overexpression of at least one biomarker in a body sample, wherein the biomarker is selectively overexpressed in ovarian cancer. In preferred embodiments, the body sample is a serum sample. The biomarkers of the invention include any genes or proteins that are selectively overexpressed in ovarian cancer, including, for example, acute phase reactants, lipoproteins, proteins involved in the regulation of the complement system, regulators of apoptosis, proteins that bind hemoglobin, heme, or iron, cytostructural proteins, enzymes that detoxify metabolic byproducts, growth factors, and hormone transporters. In some aspects of the invention, overexpression of a biomarker of interest is detected at the protein level using biomarker-specific antibodies or at the nucleic acid level using nucleic acid hybridization techniques.
