摘要:
According to an embodiment of the invention, an apparatus to detect fluorescence from a sample is disclosed. The apparatus comprises a sample plane onto which the sample is arranged, an excitation light unit including at least a light source to illuminate the sample, and a detection unit comprising at least a detector having at least 100,000 active detection elements to detect a fluorescence signal from the sample.
摘要:
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).

摘要:
The present invention relates to methods and systems for image cytometry analysis, typically at low optical magnification, where analysis is based on detection of biological particles using UV bright field, dark field or one or more sources of excitation light. The system comprises illumination means (11, 112), a sample holder (100), a sample compartment (101), imaging means (120), collection means (121), light modulation means (122, 123), and detection means (130) with active detection elements (131).
摘要:
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.
