  • Publication number: 20160131658
    Abstract: The present invention provides simple, rapid methods and procedures for analyzing cells, hereunder quantitative and qualitative assessment of cells, such as viability. The present invention relates to the use of various optionally substituted reporter compounds particularly detectable upon their reaction with thiol-containing species present in higher concentrations in intact (e.g., living) cells than in non-intact (e.g., dead, stressed and apoptotic) cells. The present invention also relates to the use of various optionally substituted reporter compounds particularly detectable upon their reaction with species present in intact and/or non-intact cells. Moreover, the present invention relates to the use of measuring techniques and/or instruments coupled with the use of various optionally substituted reporter compounds. The invention further relates to compositions used in methods for analyzing cells, such as a composition comprising N-(7-dimethylamino-4-methyl-3-coumarinyl)-maleimide (DACM).

  • Patent number: 9224031
    Abstract: The invention relates to image analysis of dark field images obtained at low magnification below 10:1. Image analysis of dark field images obtained at low magnification can be combined with analyzes of images obtained in respect of the same section of a sample and same magnification but with other techniques such as fluorescent microscopy. The system and method can be used e.g. for particle counting, particle size measurement, particle size distribution, morphology measurement, where the particles can be cells and/or cell parts. The invention also relates to a compact dark field light source unit, a system or apparatus including a microscope which by itself is compact and comprises the mentioned dark field light source unit.

  • Patent number: 9102977
    Abstract: Disclosed is a fast and simple method for quantification of nucleic acid of biological cells as 2-step protocol. In the first step cells are treated with an acidic solution containing a non-ionic detergent and a fluorescent DNA specific label. In the second step the sample may be neutralized. Determining of the content of nucleic can be performed by fluorescence microscopy. The method may also be used for obtaining information of cell cycle analysis, ploidy determination, measurements of nucleotide incorporation and assays for proliferation, health, stress level, apoptosis, necrosis, or other state of conditions of cells. The invention also relates to a kit of parts comprising an acidic agent, a detergent, a labelling agent and optionally a neutralization agent.

  • Patent number: 8411476
    Abstract: An apparatus and a method for converting power from a power input to an DC output voltage or current, which apparatus has a serial resonance converter, where a first feedback circuit is connected from the output terminal to an error amplifier, where the apparatus further has a second feedback circuit with at least one first resistor that is connected to a coil and to ground, which second feed back circuit connects the line between the first resistor and the coil and towards an inverting integrator, the output of which is connected through a second capacitor to a second input at a control circuit. As a result, the oscillating frequency is under influence of a signal that depends on the voltage generated in the resistor connected in serial to the coil or transformer.
