NAMALWA/iRFP cells are derived from the human B lymphocyte cell line NAMALWA by stably integration of a constitutive miRFP670 stably expression construct. NAMALWA cell line was derived from a patient with Burkitt's lymphoma. It is commonly used in studies related to cancer biology, immunology, and virology. NAMALWA/iRFP cells stably stably express miRFP670, can be used for in vitro assays and in vivo imaging.
