摘要： A sensor utilizing a non-leachable or diffusible redox mediator is described. The sensor includes a sample chamber to hold a sample in electrolytic contact with a working electrode, and in at least some instances, the sensor also contains a non-leachable or a diffusible second electron transfer agent. The sensor and/or the methods used produce a sensor signal in response to the analyte that can be distinguished from a background signal caused by the mediator. The invention can be used to determine the concentration of a biomolecule, such as glucose or lactate, in a biological fluid, such as blood or serum, using techniques such as coulometry, amperometry, and potentiometry. An enzyme capable of catalyzing the electrooxidation or electroreduction of the biomolecule is typically provided as a second electron transfer agent.

摘要： The present invention relates to the use of positively-charged unsymmetrical cyanine dyes, including novel unsymmetrical cyanine dyes, to stain cells and selectively stain intracellular organelles, with particular advantages in staining mitochondria. The dyes are generally weakly fluorescent in aqueous solution but highly fluorescent in cells and organelles, typically staining cells or mitochondria with a green fluorescence. The dyes stain mitochondria in both live and dead cells, and are retained in mitochondria even where the cells are treated with solvents that permeabilize cell and mitochondrial membranes. Mitochondria or cells stained according to this method are optionally stained with an additional detection reagent, such as a labeled antibody, labeled oligonucleotide, fluorogenic enzyme substrate, or other indicator for a specific cellular component or substructure, including another unsymmetrical cyanine stain of the same or different class.
