title: RNA-reverse transcriptase complex from cultured human myeloma-leukemia cells.
abstract: A high molecular weight RNA-reverse transcriptase complex in the culture media of peripheral leukocytes obtained from two Japanese patients with myeloma-leukemia was detected by demonstration of a 3H-uridine peak and a peak of DNA polymerizing activity banding at a density of 1.15-1.19g/ml. The enzyme in the complex was able to utilize poly(rA)-d(pT)10 or poly (rC)-d(pG) 12-18, but not poly (dA)-d(pT) 10 or (dT) 12-18 as template-primers. The sucrose density sedimentation analysis revealed that RNA in the complex sedimented at a location of approximately 50s and 20-30s.
