FIG. 3.

Viral RNA levels in MV-infected Vero cell and primary neuron cultures. Total RNA samples from equivalent numbers of infected Vero cells or primary CD46⁺ neurons (2 d.p.i.) were applied to a slot blot and hybridized with DNA probes recognizing MV nucleocapsid transcripts N or L, or envelope transcripts F, M, or H. Data are the percentages of phosphorimager pixel values of each MV transcript from neurons, relative to values obtained from Vero cells (set at 100% for each transcript).
