The Core Facilities Bioimaging and Flow Cytometry offers analyses of cells based on colorimetric, fluorescent, and luminescent detection by using microscopy, flow cytometry, and spectrophotometry techniques. These services enable for instance life-cell imaging/cell monitoring and high content screening of adherently growing cells. The established methods make it possible to identify around 200 different cell types in the human body with the help of specific “markers”. Isolated cell populations can be examined with regard to their function and reaction to changed environmental conditions or the mode of action of substances, drugs, etc.
