In Vitro Efficacy Evaluation

In vitro drug efficacy evaluation is an important step in drug screening, and the main indicators for evaluating the efficacy of cell therapy drugs such as CAR-T and CAR-NK usually include cell killing activity, killing specificity, cell proliferation ability, and cytokine secretion ability, among others.
