eGFP/Firefly Luciferase Ramos (RA 1) Cell Line is a Ramos (RA 1) cell line expressing firefly luciferase and enhanced GFP (eGFP) driven by an EF1a promoter. The cells were generated by transduction with Firefly Luciferase-eGFP Lentivirus (BPS Bioscience #78741), which is a SIN (self-inactivating) lentivirus.
