What is CAR-T cell therapy 

CAR T cell therapy, also known as Chimeric antigen receptor T cellI immunotherapy (CAR-T), is a tumor immunotherapy that uses genetic engineering to modify T cells in vitro. This allows them to specifically recognize tumor cells and inject those cells back into the patient to treat the disease. 

Quality control of CAR-T cell therapy technology 

CAR-T products quality control should run through the whole CAR-T cell production process, and the quality detection of CAR-T cell products is also crucial. There are many testing items,including but not limited to, cell count, activity, impurity and purity testing, assessment of biological efficacy, and general testing (e.g., sterility, mycoplasma, endotoxin,  endogenous and adventitious agents testing of virus etc.). Quality control of CAR T cell therapy is a complex and critical process, and only after comprehensive quality control can we ensure the safety and effectiveness of CAR T cell therapy, so as to provide the best treatment service for patients.
