WALTHAM, Mass., Nov. 02, 2023 (GLOBE NEWSWIRE) -- Repligen Corporation (NASDAQ:RGEN), a life sciences company focused on bioprocessing technology leadership, today announced the commercial launch of TangenX® SC, the industry’s first holder-free, self-contained Tangential Flow Filtration (TFF) device. The technology is especially suited to the manufacture of biologics where fully closed systems are critical or ideal, including antibody drug conjugates (ADCs), viral vectors, nucleic acids and lipid nanoparticles, and can also be applied to monoclonal antibody, and recombinant protein production. TangenX SC is not only transformative, it is also a milestone achievement in the advancement of downstream flat sheet TFF technology for ultrafiltration and diafiltration (UF/DF), which is performed in nearly every biopharmaceutical manufacturing process to concentrate and purify drug.

Christine Gebski, Senior Vice President, Filtration and Chromatography at Repligen, said, “TangenX SC pushes the boundaries of TFF innovation, offering clear advantages to virtually any user of flat sheet TFF. The holder-free TangenX SC device simplifies and streamlines downstream flat sheet UF/DF processes like never before. Users can trust that the quality and consistency of their TFF processes remain uncompromised while enjoying the benefits of this innovative technology.”

Compared with traditional flat sheet TFF cassettes, “plug-and-play” TangenX SC self-contained devices offer several key advantages that drive significant efficiency and productivity gains:

  • Significant time savings
    TangenX SC’s holder-free design and simplified assembly is demonstrated to reduce set up time by 80%. 
  • Reduced risk of product loss
    The novel self-contained device eliminates holders and torquing requirements, reducing the risk of product loss caused by changes in compression or cassette misalignment during installation.
  • Scalability
    TangenX SC devices scale from pilot to process scale. Designed with the same flow path length and channel geometry as traditional cassettes, TangenX SC allows users to seamlessly transition from traditional cassettes.
  • Single-use, gamma sterilized
    TangenX SC devices are aseptically closed and gamma irradiated to reduce bioburden risk and permit use in Controlled not Classified (CNC) manufacturing environments. The closed design also enhances safety by isolating operators from potentially hazardous materials.

This next-generation technology provides Repligen’s biopharmaceutical manufacturing customers with an expanded selection of flat sheet TFF offerings, beyond its TangenX SIUS® and SIUS Gamma single-use cassettes and PRO reusable cassettes.
