Investigations on the purification of small quantities of radioactively labeled foot-and-mouth disease (FMD) virus are described. The results indicated that there is present in untreated virus suspensions and pellets a complex of the 7-m mu component and cellular material, which has the same sedimentation characteristics in sucrose density gradients as the 25-m mu infective component but is disrupted by deoxycholate into smaller components that sediment much more slowly in the sucrose gradient. The ratio of plaque-forming units and complement- fixing actlvity to radioactive counts in the individual fractions in sucrose gradients of deoxycholate-treated pellets was remarkably constant, indicating that the material in the peak was homogeneous. The experiments provided substantial evidence that the virus obtained from deoxycholate-treated pellets is free from substances found in uninfected cells. (P.C.H.)
