Sony Corporation introduced a new Cell Isolation System, CGX10, which sorts cells at high speed and high purity in a closed system. The CGX10's design enables sorting of cells in a manner that is entirely closed off from the outside environment, making it possible to analyze and isolate cells while maintaining a sterile state. This is especially important in fields such as cell-based immunotherapy, which has been gaining recognition as a treatment for cancer and autoimmune disorders. To produce the cell therapies necessary for this treatment, there is an increasing demand for isolating cells with high purity and high viability in a sterile manner. It is also expected that this product could be utilized in research for developing cell-based products for fields such as cell therapy and regenerative medicine. It can also contribute to the development and production of cell therapies in compliance with quality and production management regulations (GMP*1). By introducing CGX10,Sony's Life Science business will expand from research applications to the field of cell therapies' development and manufacturing, further contributing to the advancement of cell therapy. Sony's CGX10 features the ability to use up to ten parameters to isolate a single cell, and the signal is based on excitation from four lasers (405nm /488nm /561nm /638nm), to detect target cells of interest. At analysis speeds of about 15,000 cells per second, it also ensures a purity level of about 97% and higher. By controlling fluidics, cell damage is minimized, allowing for a high viability of sorted cells. Thus, it can increase the efficiency of the downstream production processes, such as cell culture and expansion for producing cell-based therapies. Furthermore, as this instrument uses fully disposable, single-use plastic tubing/components, any risk of cross contamination between samples is avoided.

Sony is expected to begin deliveries of the CGX10 cell isolation system in Fall 2022. Main features: Closed structure that maintains sterilization -The product features Sony's proprietary closed sorting structure which maintains a sterile state and completes cell isolation inside a chip. Within the chip, after the cell has been analyzed, the selected cell will be isolated by controlling the flow of the liquid. High-speed, high-purity, high-viability cell sorting - Based on use of up to ten parameters (cell markers) obtained from excitation using four lasers (405nm /488nm /561nm /638nm), the instrument can sort a massive number of cells at high speed and with high purity. Furthermore, the user can change the priority settings for sorting. With the purity priority setting, purity will reach about 97%, and with the speed priority setting, the speed can reach roughly 100,000 cells analyzed per second. As a result, it achieves a level of productivity suitable for the mass production of cell and gene therapy manufacturing. In addition, cell damage is minimized by proper control of the liquid. This ensures a high viability of cells, which increases efficiency in the next stages, such as gene transduction or culturing of the isolated cells. High operability: The CGX10 instrument is equipped with a touch LCD touch display panel allowing seamless and intuitive operation of the hardware alongside the software. In addition, there are two types of software modes: the "process development mode" and the "standard operation mode." In the "process development mode," detailed settings and customizations are possible, allowing the user to create instruction sets. The "standard operation mode" will automatically sort cells based on the instructions set in the "process development mode." Multiple instruction sets can be developed on a given instrument and transferred to multiple instruments for production. "Standard operation mode" includes functionality suitable for GMP manufacturing and has a function to record operation history. Employing a single-use disposable tubing kit: The tubing kit includes a plastic tube specifically made for controlling the liquid that comes in contact with the sample. This single-use disposable tubing is intended to be replaced after each use. A new tubing kit can be used for each patient, avoiding contamination between samples. Documentation support for GMP manufacturing: This instrument is designated for use in cell-based immunotherapy settings including gene therapy, as well as cellular manufacturing for GMP regenerative medicine. Sony will provide user support by distributing the compliance support documentation necessary for GMP manufacturing, such as the CoA (analysis certificate), animal-free production certificate, and product information files.
