Levels of mRNA of E1A and E1B over increasing cell culture passages for MDCK-E1 clone #106 (a) and #139 (b).
<p>The gene expression was determined by Real Time reverse transcriptase PCR normalized to the housekeeping gene (GAPDH). Error bars represent a 10% variability error associated with the method.</p
Cell specific productivity of HD CAVGFP and corresponding contamination with helper JBΔ5.
<p>Errors correspond to 25% inter-assay variability. The contamination levels of JBΔ5 correspond to the ratio between the I.P titers of JBΔ5 and HD CAVGFP.</p
Half maximal inhibitory concentrations (IC50) of MDCK-E1 and MDCK-E1-Cre cell clones in response to increasing concentrations of <i>tert</i>-butyl hydroperoxide (<i>t</i>-BHP) (causing oxidative stress injury) in the culture medium.
<p>MDCK-E1#121 and MDCK-E1#106 represent high and low E1B expression, while MDCK-E1#106-Cre#10 and MDCK-E1#106-Cre#19 represent high and low Cre-activity, respectively. Error bars correspond to standard-deviation of quadruplicate assays. *<i>p</i><4×10<sup>−5</sup>, **<i>p</i><0.05, ***p<0.04, indicating the significance of a single factor Anova analysis.</p
Amplification of CAVGFP and JBΔ5 in Cre-expressing clones and the corresponding parental cells.
<p>The error in amplification ratio corresponds to 25% inter-assays variability. The productivity ratio corresponds to the ratio between CAVGFP amplification using Cre expressing and corresponding parental cells. Fold decrease in JBΔ5 production was calculated using the ratio between amplification value of parental cells (MDCK-E1#106 and DKZeo) and the corresponding Cre-expressing cells. Excision efficiency was calculated assuming that the difference in the amplification ratio of parental and corresponding Cre-expressing cells corresponds to unpackaged viral genomes.</p
Virus amplification in MDCK-E1 clones and DKZeo cells.
<p>The error corresponds to 25% inter-assays variability.</p
Cell specific Cre activity of MDCK-E1#106-Cre subclones and DKCre cells measured indirectly through a luciferase assay (see materials and methods).
<p>Error assumes 20% inter-assay variability.</p
