Yokogawa Electric Corporation announced that it has developed the Single Cellome System SS2000, a single-cell analysis solution that utilizes high-resolution images captured with a confocal microscope to collect samples of specific cells and intracellular components automatically and accurately. The SS2000 will be released in Japan, the US, and China in February 2022, with release in other markets, such as Europe to follow at a later date.
Conventional techniques for the analysis of intracellular components have typically involved the disruption and collection of heterogeneous cell populations, which does not allow for sampling at the individual cell level, so many components cannot be collected, and essential information on cell location and morphology is lost. In addition, as this sampling is done manually, throughput is low, and it is quite difficult for even experienced researchers.
Utilizing Yokogawa's core imaging technologies that enable the real-time analysis of minute phenomena in live cells, the Single Cellome System SS2000 incorporates new technologies that automatically and accurately control sampling operations in order to support the performance of cutting-edge life science research. Yokogawa confocal microscopy technology enables the rapid, minimally invasive imaging of living cells. Based on the high-sensitivity analysis of the high-resolution 3D images, the cells are automatically and precisely sampled using precise positioning technology.
Optimal selection of cells, or regions within cells, according to set criteria： The SS2000 analyzes images of a large number of cells within a target range and classifies them by using provided criteria such as cytoplasm area and nucleus size. It then identifies which cells are suitable for analysis and determines their sampling location. Utilizing criteria, such as distance from the nucleus, image analysis can even identify optimal regions within individual cells.
Reliable sampling of target cells and components within individual cells： The SS2000 directly samples only target cells without detachment, retaining all positional and morphology information in the culture plate. Furthermore, the utilization of high-resolution 3D images and precise positioning technology enables the selective sampling of target organelles and cytoplasm.
Samples can be used for a broad range of analyses： The collected cells and intracellular components can be used for a broad range of analyses, including genetic analysis and mass spectrometry. The optimum and efficient collection of target samples improves analytical sensitivity. In addition, single living cells that have been sampled can be grown in secondary cell cultures.
