Advancing your pluripotent stem cell therapy research to clinical applications requires careful material selection as the quality of starting materials significantly impacts the properties of your final stem cell therapy product.

At Thermo Fisher Scientific, we have developed Gibco Cell Therapy Systems (CTS) products across the pluripotent stem cell therapy workflow to ease the transition from discovery to commercial manufacturing. We offer high quality GMP manufactured, commercial scale ancillary materials with a high degree of qualification, traceability, and regulatory documentation.

  • Scalable manufacturing under GMP conditions - Gibco media and supplements are manufactured in conformity with Good Manufacturing Practices (GMP) for medical devices, 21 CFR Part 820, and follow USP<1043> and Ph Eur 5.2.12, and our manufacturing sites are FDA-registered and ISO 13485- and/or ISO 9001-certified. Our investment in rigorous product manufacturing ensures the consistency, reliability, and high quality of PSC therapy reagents in combination with the ability to scale up and accommodate changing needs.
  • Quality control testing and regulatory documentation - CTS media and reagents help minimize the risk of contamination and variability in your research with extensive safety testing, including sterility, endotoxin and mycoplasma. Full traceability for raw materials is also available, including Drug Master Files and/or Regulatory Support Files, and certificates of origin.
  • Proven use for a seamless transition from research to clinic - We offer an extensive selection of serum-free, xeno-free, or animal origin–free formulations with cell therapy specific intended use statements and complementary research use reagents. Our CTS products have been used in over 200 clinical trials as well as in commercially approved cell therapies including FDA-approved CAR-T therapies and the first FDA-approved therapeutic cancer vaccine.

Gibco CTS Rotea Counterflow Centrifugation System
