Established in 1963 from Burkitt?s lymphoma in an 11 year old black male. Growth is in the form of single cells without attachment and as macroscopically visible clumps containing many hundreds of cells. Resistant to VSV. This cell line carries the latent Epstein-Barr Virus (EBV) genome and is positive for EBNA. RAJI is sometimes referred to as a ?non-producer?; the EBV genome carries deletions attributed to preventing the formation of virus particles.
