  • Patent number: 11513328
    Abstract: A method and microscopy system are useful for recording an image of a sample region. A laser beam is directed onto the sample region with interface(s). An objective lens facilitates images the laser beam on a focusing point which lies on the optical axis of the objective lens or an axis parallel thereto, and which lies in a focusing plane. The objective lens and the sample region are displaced with respect to one another in relative fashion along the optical axis of the objective lens to different relative displacement positions. Intensity values of the laser beam are captured for a respective relative displacement position. A respective highest intensity value for a respective displacement position, a curve of the highest intensity values, and a reference relative displacement position from at least one maximum of the curve, are determined. Image(s) of the sample region is/are captured at the reference relative displacement position.

    Abstract: An incubation device has multiple rocking platforms with each platform pivotally mounted about a respective axis. Each rocking platform has a respective receiving device for mechanically reversibly receiving a respective incubation channel. The device also has a common drive unit for common respective rocking movements of each platform from a zero position through with a specific angle range as a result of movement of the drive unit. Each rocking platform is coupled to the drive unit via a respective coupling mechanism, and each coupling mechanism elastically and resiliently couples the respective rocking platform to the drive unit, such that when the rocking platform is restrained, despite continuation of the drive movement, the rocking platform remains motionless in a fixed position. After release of the restraint on the rocking platform, the rocking platform resumes the rocking movement with the specific angle range.

  • Patent number: 11305289
    Abstract: A method is useful for automated detection of antibodies in a liquid biological sample with an antigen chip having antigen spots which are applied thereon and which have an identical, common dye. The antigen spots form respective antigen spot sets which form corresponding respective, regular antigen spot patterns. Furthermore, reference spots comprising the identical dye are applied, and form a reference spot set which forms a regular reference pattern. The reference pattern differs with respect to its regularity from the antigen spot patterns. Through a first image information item which represents a color of the reference spots and of the antigen spots due to the identical, first dye and through a second image information item which represents a potential color of the antigen spots due to a second dye after an incubation, binding of antibodies of the biological sample to respective antigen types is then determined by image processing.
