CAR-T therapy has emerged as a groundbreaking approach in the immunotherapy landscape. Given the complexity and specificity of CAR-T therapy, the production of high-quality materials such as in vitro transcribed RNA (IVT RNA) is crucial. IVT RNA plays an essential role in delivering genetic information into T cells, facilitating the expression of CARs. At Creative Biolabs, we are committed to providing top-tier IVT RNA manufacturing services specifically optimized for CAR-T applications. Our advanced platform ensures precision and efficiency, supporting researchers and clinicians in the development and deployment of cutting-edge CAR-T therapies.

Why should I choose the mRNA platform over established lentiviral vectors for my early-stage CAR-T research?
mRNA offers rapid, cost-effective production and, critically, transient expression, which provides an intrinsic safety switch for managing early toxicity. Furthermore, our non-viral method eliminates the risk of insertional mutagenesis associated with integrating vectors, streamlining your regulatory de-risking process.
How scalable is Research Grade mRNA production, and what is the path to GMP manufacturing?
Our RG platform is inherently scalable, moving easily from milligram-scale for early research to multi-gram quantities required for clinical development. The core synthesis and purification processes utilized in our RG service are designed to be compatible with our GMP manufacturing protocols, ensuring a smooth, low-risk technology transfer when you are ready to advance to clinical trials.
What measures does Creative Biolabs take to address the concern of mRNA immunogenicity?
Immunogenicity is primarily driven by double-stranded RNA (dsRNA) contaminants. We employ advanced multi-step purification techniques, including HPLC and TFF, to ensure the final mRNA product achieves exceptional purity, significantly minimizing dsRNA levels and ensuring a low innate immune response in your sensitive cell cultures.
Using Creative Biolabs' Research Grade (RG) CAR-T mRNA Manufacturing Service in our preclinical safety assays has significantly reduced off-target cytokine release. The removal of dsRNA contaminants was clearly superior to our in-house IVT methods, resulting in cleaner T cell profiles and more reliable in vivo data. Dr. La FD.
The transient nature of the CAR-T mRNA facilitated toxicity modeling in our solid tumor program. We could precisely control the duration of CAR expression, which was invaluable for establishing a crucial safety window and allowed us to mitigate potential CRS risks before moving to stable transduction methods.
