Background: For the last 40 years, the technique of extracorporeal photopheresis (ECP) has constantly developed. Among irradiation systems, those called "off-line" allow the validation of the quality of the cell therapy product. The inhibition of the proliferation of lymphocytes after ultraviolet irradiation (UVA) is usually verified by the tritiated thymidine assay as in vitro proliferation assay.
