GIBCO OpTmizer™ CTS™ T-Cell Expansion SFM has been developed for the growth and expansion of human T lymphocytes. OpTmizer™ CTS™ T-Cell Expansion medium is a complete serum-free, xeno-free 1X medium consisting of OpTmizer™ T-Cell Expansion Basal Medium (1 L bottle) and OpTmizer™ T-Cell Expansion Supplement (26 mL), which are mixed together prior to use.

- Maintains similar phenotype and function (e.g., cytokine secretion profile) of polyclonally activated and cultured T cells as observed for conventional serum supplemented medium

- Consistent performance in supporting T cell expansion

- Supports high density T cell culture (e.g., >3×10⁶ CD3+ T cells/mL) in static culture
  
  With OpTmizer™ T-Cell Expansion SFM, we offer both basic and clinical research communities a new tool to enhance their success in growing human T-cells. It is specially formulated to allow for superior cell growth & viability, less variability and more consistent results, and easier transition from research to clinical applications.
  
  Workflow benefits:

- Minimizing the need to handle purchasing, storage, qualification of serum and thus reducing variability and costs

- More rapid T cell expansion, thus reducing cycle time and improving productivity

- Complete serum-free, xeno-free medium, allowing for a seamless transition from research to clinical applications and minimizing regulatory workload
