ALyS™505N is a serum-free and xeno-free medium used for the expansion and activation of human lymphocytes. It is available in four different IL-2 concentrations, suitable for activating or expanding T cells from human lymphocytes. Higher concentrations of IL-2 activate T cells, while lower concentrations are used for expansion. Gas-permeable culture bags are available for IL-2-free and 175 uL/mL media. Additionally, higher cell proliferation can be achieved by adding a small amount of Artificial Serum.

ALyS™705 is a serum-free, animal-free, and chemically defined medium used for the expansion and activation of human lymphocytes. Unlike ALyS™505N, ALyS™705 achieves an animal-free culture environment by utilizing a high molecular weight polymer instead of albumin, which reduces shear stress between cells. When supplemented with Artificial Serum, ALyS™705 has demonstrated higher proliferation rates than ALyS™505N.

Lymactin-T, an anti-CD3 monoclonal antibody produced by the hybridoma OKT3 in a serum-free environment, complements the ALyS™505n & 705. It induces strong proliferation by binding to CD3 on T cells derived from peripheral blood, enhancing the activation and expansion process.
