Why Top CGT Developers Choose Kryogene™ for CAR-T & Stem Cell Freezing?

2025.08.30

In the fast-evolving field of cell and gene therapy (CGT), cryopreservation isn’t just about cell survival—it’s about preserving functionality, potency, and therapeutic efficacy. Kryogene™ CFM-CGT has become the trusted choice for leading CGT developers, ensuring that CAR-T and stem cells maintain their critical attributes post-thaw.

1. Unmatched Post-Thaw Viability & Functionality

· CAR-T Cells: Kryogene™ maintains >98% CAR expression post-thaw, with no loss in cytokine secretion (IFN-γ, IL-2) upon activation—critical for sustained anti-tumor activity.

· Stem Cells (MSCs/hPSCs): Ensures >95% viability while preserving key markers (CD73+/CD90+/CD105+) and differentiation potential (osteogenic, adipogenic, chondrogenic).

2. Regulatory-Compliant & Scalable

· FDA Master File (DMF 040563) & cGMP Manufacturing: Guarantees batch-to-batch consistency for seamless IND/BLA submissions.

· Animal Component-Free & Ultra-Low Endotoxin (<0.5 EU/mL): Minimizes immunogenicity risks, making it ideal for clinical use.

3. Optimized for High-Density & Large-Scale Use

· Supports High Cell Densities: Validated for CAR-T (up to 2.5E+7 cells/mL) and MSCs (5E+6 cells/mL).

· Closed-System Compatibility: Works flawlessly with cryobags, vials, and automated fill-finish processes.

4. Beyond Survival—Functional Resilience

· Faster Recovery: CAR-T cells expand 1.5× faster post-thaw compared to conventional media.

· Stem Cell Potency: MSCs retain their doubling time (25–30 hrs) and differentiation efficiency (90% adipogenic/osteogenic capacity).

5. Ready-to-Use & Workflow-Friendly

· Pre-Formulated DMSO: Eliminates manual errors in cryoprotectant preparation.

· Validated Freezing Protocols: Controlled-rate freezing (-1°C/min) and rapid thaw (37°C) maximize cell recovery.
