Hillgene's NKand TIL Cell Expansion Reagent (Feeder cell) is an irradiated and inactivated engineered K562 cells expressing IL-21 and other cytokines, which, together with the mainstream immune cell culture medium, can activate and expand NK cells and tumor-infiltrating TIL cells derived from umbilical cord blood and peripheral blood mononuclear cells cultured in vitro, and the purity of the obtained NK and TIL cells is high.
Usage Scenarios
·Suitable for activation and mass expansion of different immune cells such as NK cells, CAR-NK cells and TIL.
·Process Development Stage: Evaluate the in vitro expansion capacity of cells such as NK and TIL and optimize the process during the early development stage of cell therapy products.
·Process locking, product production and comparability study phase: During the mid-term process locking, production and cell process change phase after IND approval for cell therapy products, establish stable cell expansion processes based on trophoblast cells, such as NK and TIL, and carry out process locking, cellular drug production and comparability studies for cell products.
