Table 2. Levels of inhibition of the mRNA and protein expression of viral genes in cells expressing ribozymes, as compared to the levels of inhibition in cells that did not express a ribozyme (U251).

The values are derived from experiments that were performed in triplicate and repeated three times. The values of standard deviation for these results are less than 5%.
