  • Publication number: 20080318270
    Abstract: In a process for the quantitative optical analysis of fluorescently labelled biological cells 5, a cell layer on a transparent support at the bottom 2 of a reaction vessel 1 is in contact with a solution 3 containing the fluorescent dye 4. The sensitivity of analytical detection can be considerably improved if to the fluorescent dye 4 already present in addition a masking dye 9, which absorbs the excitation light 6 for the fluorescent dye 4 and/or its emission light 7, is added to the solution 3 and/or if a separating layer 10 permeable to the solution and absorbing and/or reflecting the excitation light 6 or the emission light 7 is applied to the cell layer at the bottom 2. This process can also be used for improving the sensitivity in the quantitative optical analysis of a luminescent biological cell layer. The separating layer 10 must in this case be composed such that it has a high power of reflection for the luminescent light 11.

  • Patent number: 7138280
    Abstract: In a process for the quantitative optical analysis of biological cells labelled with a fluorescent dye, the sensitivity of analytical detection can be considerably improved if a masking dye, which absorbs the excitation light for the fluorescent dye and/or its emission light is added to the solution surrounding the biological cells and/or if a separating layer permeable to the solution and absorbing and/or reflecting the excitation light or the emission light is applied to a layer of the biological cells at the bottom of a reaction vessel. This process can also be used for improving the sensitivity in the quantitative optical analysis of a luminescent biological cell layer. Analogously, these process principles can also be used in receptor studies for the masking of the interfering background radiation in the quantitative optical analysis of fluorescently or luminescently labelled reaction components.

  • Patent number: 6984297
    Abstract: A method and a device are used for carrying out measurements on cells located in a liquid environment. Each cell is positioned with an underside of its membrane on a surface having a channel running through it. A negative pressure is established to aspirate the cells. Each cell is electrically scanned via at least one electrode which is spaced apart from the cell. The negative pressure is preferably established in a pulse-like manner to rupture the membrane in such a way that the cell interior enclosed by the membrane is connected to the channel.
