Yokogawa has announced that it has obtained a label-free image analysis technology from Chip-Man Technologies of Finland. Using this technology, detailed computer analyses can be conducted of live cell images that have been taken with a microscope using a label-free technique.
In basic research, live cells are typically labelled with a dye and then irradiated by a laser so that they can be observed more easily under a microscope. However, this exposure to light often has a phototoxic effect on the cells. Therefore, during the clinical trials that are required for regulatory approval, it is necessary to carry out label and irradiation-free observations of in vivo cell activity. Cells that are being cultured for transplantation must also be label-free. Yokogawa has acquired this technology to strengthen its capability in applications such as in vitro fertilisation (IVF) and the coagulation and organisation of differentiated cells in regenerative medicine, where quality and safety are utmost concerns.
