Originally described to be derived from the tumor-containing left axillary lymph node of a 39-year-old white man with small lung cell carcinoma (T3 N3 M3) in 1989; however, DNA fingerprinting and cytogenetic analysis showed cross-contamination with cell line RPMI-8226; RPMI-8226 was established from the peripheral blood of a 61-year-old man with multiple myeloma (IgG lambda-type) at diagnosis in 1966
