Possible Species Differences in RNA Metabolism of Lymph Node Cells

Differences in the rates of incorporation of tritiated uridine U-H³ of lymph node cells of different species have been found. Plasma cells from humans, guinea pigs, mice, and rabbits have a higher rate of incorporation of U-H³ than do plasma cells from rats, whereas human blast cells have a lower rate of U-H³ incorporation than blast cells from the various rodents.
