Daudi/iRFP cells are derived from the human Burkitt lymphoma cell line Daudi by stably integration of a constitutive miRFP670 stably expression construct. Daudi cells have been widely used in B-cell biology, immunology, cancer research and drug development. Daudi/iRFP cells stably express miRFP670, can be used for in vitro assays and in vivo imaging.
