Abstract: The invention relates to a method for selecting an expressed sequence from a library, comprising the following steps: Each of a plurality of eukaryotic cells comprising a cell wall comprises a nucleic acid sequence member of a library, which is expressed as a target membrane protein in said eukaryotic cells. The cell wall of the cells is permeabilized. The penneabilized cells are labeled with a ligand capable of binding to the target membrane protein. The ligand bears a detectable label. A subset of the labelled cells is selected as a function of detectable label present. Finally, an expressed nucleic acid sequence is isolated from said selection of cells in an isolation step.

Abstract: Various aspects of the present disclosure relate to a surgical microscope system, and in particular, to an arm for a surgical microscope system. The surgical microscope system comprises an optics carrier comprising optical components of a microscope of the surgical microscope system. The surgical microscope system comprises a display device for displaying image data recorded by an optical imaging sensor of the surgical microscope system. The surgical microscope system comprises an arm. The arm comprises a first section and a second section. The first section is configured to provide a vertical and/or lateral adjustment of the position of the optics carrier. The second section is attached to a suspension point of the first section and to the optics carrier.

Abstract: Examples relate to a surgical microscope system, and to a system, a method and a computer program for a surgical microscope system. The system comprises one or more processors and one or more storage devices. The system is configured to obtain intraoperative sensor data of at least a portion of an eye from a Doppler-based imaging sensor of the surgical microscope system. The system is configured to process the intraoperative sensor data to determine information on a blood flow within the eye. The system is configured to generate a visualization of the blood flow. The system is configured to provide a display signal to a display device of the surgical microscope system based on the visualization of the blood flow within the eye.

Abstract: The invention relates to a surgical microscope stand (100) encompassing: a first carriage (16) that is arranged on a first carrier arm (14) and is drivable by a first drive unit; and a second carriage (18) that is arranged on a second carrier arm (22) and is drivable by a second drive unit. The surgical microscope stand (100) further encompasses an operating region (34) within which at least one operating unit for manual application of control to the first and second drive units is provided.

Abstract: The invention relates to an illumination unit that encompasses two light sources arranged one behind another in a channel . A cooling unit is provided respectively at the two ends of the channel. The invention further relates to an energy supply unit for supplying the illumination unit with electrical energy. The energy supply unit encompasses two energy sources arranged in a channel. Respective cooling units are arranged at the two ends of the channel.
