  1. NT – no measurable titre and not included in statistical analysis
  2. N/A – not applicable
  3. The mean is the average of all measurable titre within each experiment for each cell line. The SD is the standard deviation of all measurable titre within each experiment for each cell line. Mean ± SD was not calculated for DF-1 ABBV-1 because there was either no measurable titre or only one measurable titre
  4. * P < 0.05, ** P < 0.01. P value indicates statistical significance between CCL-141 ABBV-1 and QT-35 ABBV-1. Statistical analysis was not performed on DF-1 ABBV-1 due to lack of measurable titre for all but one passage
