Bio-Rad Laboratories, Inc. (BIO) Showcases S3™ Cell Sorter at American Society for Cell Biology

12/19/2012 10:25:16 AM

Hercules, CA — December 15, 2012 — Bio-Rad Laboratories, Inc. will showcase its S3 cell sorter at the American Society for Cell Biology (ASCB) Annual Meeting (booth #3) at the Moscone Center, San Francisco, December 15–19. This will be the first public showing of the instrument as a Bio-Rad product since the acquisition of the Avalon system from Propel Labs in October.

Six “early access” S3 cell sorters have been installed in research laboratories in North America. One of the first labs to receive the instrument was the Broad Center Cell Analysis and Sorting Facility at the Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research at the University of California, San Francisco.

“Our lab was interested in testing the S3 cell sorter because of the innovative way it handles setup and QC as well as its overall usability,” said Michael Kissner, core manager at the Broad Center.

The Broad Center is using the S3 cell sorter for a variety of cell types, including embryonic stem cells and tumor cells isolated primarily by fluorescent protein labeling. The cells have been used for various downstream assays including molecular analysis and cell culture experiments. The instrument will also be used to sort cells to establish stable cell lines after transfection.

“We’ve received positive comments from all of the researchers who have used the S3 cell sorter,” said Kissner. “Everyone is impressed at how well the instrument works and how user-friendly it is. The overall performance has been fantastic.”

Bio-Rad will host a special event at 7 PM on Dec. 17 at the Westin St. Francis San Francisco on Union Square. The event will feature speaker John C. Tigges, the technical director of the Flow Cytometry Core at the Harvard Stem Cell Institute.

Tigges uses the S3 cell sorter to isolate regulatory T cells (Tregs) for transplant medicine. He believes the S3 cell sorter’s ease of use, small footprint, and gentleness on cells during sorting can lead to a breakthrough in bringing Tregs closer to clinical applications by increasing the number of viable Tregs that can be tested to monitor the immune response during transplantation.

Bio-Rad will begin shipping to fulfill orders for the S3 cell sorter starting in January 2013.

About the S3 Cell Sorter

The S3 cell sorter is an automated, easy-to-use, benchtop cell sorter equipped with one or two lasers, forward and side scatter detectors, and up to four fluorescent detectors. The new ProDrop™ technology automates setup and calibration in less than 30 minutes, which allows researchers to quickly sort samples at high speeds while maintaining sensitivity and high purity. The S3 cell sorter also has a compact benchtop footprint and comes with the intuitive and lab-friendly ProSort™ software package.

Cell sorting systems are used primarily in flow cytometry core facilities at academic, government, and industrial research institutions due to the size, high cost, and complexity of the operation and maintenance of flow cytometry instruments. The simplicity of operation and price point of the S3 cell sorter will make cell sorting more accessible to new labs and core facilities that previously could not afford or support a flow cytometry instrument.
