Lonza’s R&D efforts and collaboration with many clinical trials have provided Lonza with the tools and expertise to support the developments in adoptive immunotherapy, cancer therapy, genetic therapy and other cellular therapies.

Lonza’s philosophy for the development of serum-free formulations for use in cellular therapy is to provide a nutritionally complete and balanced environment for the cells. We have not included any exogenous growth factors, artificial stimulators of cellular proliferation or undefined supplements.

The products are devoid of any protein-kinase C stimulators and are suitable for the investigation of second messenger systems in the activation of human and murine lymphocytes. The formulations are complete and contain pharmaceutical grade human albumin, recombinant human insulin and pasteurized human transferrin.

All X-VIVO medium products are manufactured under current GMPs and are listed with the FDA in a product Master File. Permission to cross-reference the Master File may be obtained by contacting the Product Manager.

X-VIVO 10 medium

The X-VIVO 10 medium formulation is designed to support the generation of Lymphokine Activated Killer (LAK) cells in a serum-free environment. The original protocols involved the incubation of patient or normal donor Peripheral Blood Lymphocytes (PBL) at 1.0-3.0 x 106 cells/mL for a period of 3 days in the presence of 1,000 Cetus units of rIL-2/mL. Optimal LAK cell generation is achieved when peripheral blood lymphocytes are incubated for three to ten days at a density of 1.0-6.0 x106 cells/mL in the presence of 100-1000 Cetus units of rIL-2. X-VIVO 10 medium is available as a 1X liquid in several convenient configurations.

X-VIVO 15 medium

X-VIVO 15 medium is similar in composition to X-VIVO 10 medium and has been optimized for the proliferation of Tumor Infiltrating Lymphocytes (TIL) under serum-free conditions. The formulation supports the proliferation of purified CD3+ cells isolated from peripheral blood and human tumors. X-VIVO 15 medium has also been used to support the growth of human monocytes, macrophage cells and cell lines, PBL, granulocytes and natural killer (NK) cells. In addition, X-VIVO 15 medium provides a serum-free environment for the expansion of HUT-78 and related human lymphocytic cell lines.

X-VIVO 20 medium

X-VIVO 20 medium was developed and optimized to support the generation of LAK cells from monocyte-depleted PBL at high density. Initial cell densities between 2.0-3.0 x 107 cells/mL were successfully used to generate LAK cells. X-VIVO medium 20 may also be used as a growth medium for PBL and TIL.

Other applications of X-VIVO products include:

  • Proliferation of PBL
  • Proliferation of TIL
  • Cryopreservation and transplantation of organs
  • Cultivation of human monocytes and macrophages
  • Cultivation of stem cells
  • Cultivation of dendritic cells
