Repligen Launches Single-Use XCell™ ATF System for Bioprocess Intensification

Posted on: 05 Oct 16
  • Complements Stainless Steel ATF Technology with Innovative Single-Use Format
  • Improves Ease of Use for Biopharmaceutical Manufacturing Customers
  • Offers Equivalent High Performance to Stainless Steel XCell™ ATF With Faster Implementation

WALTHAM, Mass., Oct. 05, 2016 (GLOBE NEWSWIRE) -- Repligen Corporation (NASDAQ:RGEN), a life sciences company focused on bioprocessing technology leadership, today announced the commercial launch of its single-use version of XCell™ ATF, a proprietary cell retention system used by biologic drug manufacturers to intensify cell culture and improve the efficiency and productivity of upstream processes. This innovative new single-use format, which will be offered alongside the existing stainless steel line, significantly reduces implementation time and improves overall ease of use for Repligen’s biopharmaceutical manufacturing customers. The new XCell ATF format aligns with single-use and continuous processing workflows that biomanufacturers are increasingly adopting for their flexibility, convenience and cost-saving advantages.

The single-use XCell ATF will be formally introduced at Biotech Week Boston, taking place October 4-7 at the Boston Convention and Exhibition Center. Repligen will initially offer the single-use version of XCell ATF in sizes suitable for lab-scale and production-scale biopharmaceutical manufacturing. Additional information and features of this technology can be found on Repligen's website.

Christine Gebski, Vice President Product Management and Field Applications said, “We expect the availability of XCell ATF technology in a convenient, gamma-sterilized, single-use format to drive increased evaluation and penetration of this perfusion tool in the marketplace. In beta site evaluations, the single-use format reduced implementation time by over 80% while delivering consistent high performance, equivalent to the stainless steel format.”

Tony J. Hunt, President and Chief Executive Officer said, “Since we acquired the ATF technology in 2014, the ATF product group has been a strong driver of growth for the Company. With this launch, Repligen is enabling increased implementation of perfusion-based systems in upstream continuous processing. As we extend the XCell ATF line to align with single-use workflows, we continue to deliver products that improve process economics and efficiencies for our customers.”

About the XCell™ ATF System
The XCell™ ATF System is a filtration device that attaches to a bioreactor and is used by many of the world's largest biopharmaceutical companies and contract manufacturing organizations to improve productivity during the cell culture step of biomanufacturing. The XCell ATF System routinely increases cell densities to 2- or 3-times the levels achieved by standard batch processes. As a result, product yield is increased which improves facility utilization and can reduce the size of bioreactor required to manufacture a given volume of biologic drug product.

The XCell ATF System is available in a range of sizes from lab-scale through to commercial manufacturing in both stainless steel and single-use formats. Repligen is initially offering the single-use format device in two sizes: the XCell ATF 2 (lab-scale) and the XCell ATF 6 (production-scale).
