Cell Therapy Systems (CTS) OpTmizer T Cell Expansion Serum-Free Medium (SFM), no phenol red

Gibco™ CTS™ OpTmizer™ T Cell Expansion SFM, no phenol red and the CTS™ Dynabeads™ CD3/CD28 have a proven track record of scaling up, and together they can help simplify your transition into clinical and commercial manufacturing.

Developed with cell performance at the forefront, this serum-free and xeno-free medium supports the growth and expansion of human T lymphocytes in multiple culture formats.

CTS OpTmizer T Cell Expansion SFM, no phenol red:

• Supports high-density T cell culture (>4 x 10⁶ CD3 T cells/mL), including CAR T cells
• Supports T cell activation using Gibco™ Dynabeads™ products, stimulatory or artificial antibody-presenting cells, and soluble antibody protocols
• Supports phenotype, functions (e.g., cytokine secretion profile), and viability similar to T cells cultured in conventional medium supplemented with FBS or human AB serum

CTS Dynabeads™ CD3/CD28

CTS Dynabeads CD3/CD28 simultaneously isolates and activates T cells based on CD3 and CD28 co-expression and allows you to achieve desired naive and early memory phenotypes. T cells are isolated with high recovery (>90%) and purity (>95%) with uniform stimulation (>95% CD25⁺ at day 3 post-activation). Activated and expanded T cells preserve a young phenotype (CD28⁺ CD62L⁺) with low PD-1 expression at days 7–10, as well as a demonstrated increase in clonal diversity compared to starting T cells.
