CelTheraTM GMP T Cell Expansion Medium is a serum-free culture medium designed specifically to support the cultivation of human T cells. It is a GMP-produced T cell maintenance and expansion medium that is free of serum and animal origin.
Animal origin-free culture media can enhance batch-to-batch consistency, prevent T cell overactivation by unknown serum components, and lower the risk of introducing potentially harmful microorganisms during the culture process more effectively than traditional culture media or xeno-free culture media.
In addition to maintaining the high fold expansion of T cells, CelTheraTM GMP T Cell Expansion Medium does not require the addition of any serum or serum replacements. Specific T cell applications should dictate the dosage if users decide to add serum or serum replacement.

Features
- Serum-free, animal origin-free (AOF), and free of exogenous growth factors.
- Designed to support low-density seeding and high fold expansion of T cells.
- Suitable for large-scale T cell expansion.
- No additional serum or serum replacements needed.
- Maintains T cell phenotypes comparable to media supplemented with serum or serum replacements.
- Contains only recombinant proteins, with no antibiotics included in the formulation.
- Produced in compliance with current GMP guidelines.
Storage
The CelTheraTM GMP T Cell Expansion Medium is stable for 18 months when stored at 2–8 °C and protected from light. When stored at -20 °C or lower and shielded from light, the CelTheraTM GMP T Cell Expansion Supplement remains stable for a full year.

Application data
T cell viability and growth rate in different media
Image Credit: ACROBiosystems
T cells isolated from PBMCs of three different donors were activated and cultured for 11 days in various media, each supplemented with 300 IU/mL Acro GMP IL-2 (Cat. No. GMP-L02H14). Cell count and viability were assessed on days 6, 8, and 11 using trypan blue staining. The results showed that cells cultured in Acro T cell medium (Cat. No. GMP-CM3101) exhibited a higher proliferation rate and greater viability compared to those in the other two media.
Tcm ratio across different media

T cells isolated from PBMCs of three different donors were activated and cultured in various media supplemented with 300 IU/mL Acro GMP IL-2 (Cat. No. GMP-L02H14). The percentage of central memory T cells (Tcm, CD45RO+/CCR7+) was assessed by flow cytometry once the cells reached approximately 50-fold expansion. The results showed that cells cultured in Acro T cell medium (Cat. No. GMP-CM3101) had a higher proportion of central memory T cells compared to those in the other two media.
Efficiency of lentivirus transduction in different media

T cells isolated from PBMCs were activated and cultured in various media supplemented with 300 IU/mL Acro GMP IL-2 (Cat. No. GMP-L02H14). Twenty-four hours after activation, the cells were transduced with pLenti-CMV-EGFP-puro lentivirus at an MOI of 3 or 6. After another 24 hours, the lentivirus was removed by centrifugation, and the cells were cultured for an additional 48 hours.
Flow cytometry analysis of the CD3+eGFP+ population indicated that cells cultured in Acro T cell medium (Cat. No. GMP-CM3101) exhibited a lentiviral transduction efficiency comparable to that of the other medium.
Multiple donor verification

Human PBMCs were cultured for two weeks in either CelTheraTM GMP T Cell Expansion Medium (ACROBiosystems, Cat. No. GMP-CM3101) or a competitor's T cell culture medium (Competitor L + 2.5 % SR), both supplemented with GMP Human IL-2 Protein (ACROBiosystems, Cat. No. GMP-L02H14).
The results indicate that CelTheraTM GMP T Cell Expansion Medium performs comparably to Competitor L + 2.5% SR, with notably better cell expansion observed in CelTheraTM GMP T Cell Expansion Medium (ACROBiosystems, Cat. No. GMP-CM3101).
Large-scale culture verification

Human PBMCs were activated using 0.2 µg/mL GMP Monoclonal Anti-Human CD3 Antibody (OKT3) (ACROBiosystems, Cat. No. GMP-MC0323) and 1 µg/mL GMP Monoclonal Anti-Human CD28 Antibody (ACROBiosystems, Cat. No. GMP-MC2824). The cells were then cultured for two weeks in CelTheraTM GMP T Cell Expansion Medium (ACROBiosystems, Cat. No. GMP-CM3101) supplemented with 500 IU/mL GMP Human IL-2 Protein (ACROBiosystems, Cat. No. GMP-L02H14).
The results demonstrate that this combination of GMP reagents and CelTheraTM GMP T Cell Expansion Medium is suitable for large-scale T cell culture in a 3L system, efficiently expanding cells while maintaining high viability.
