Trypan blue-based survival assay. U251 and SNB19 cultures were infected with wtHAdV-5 or RL-07 with a MOI of 100. Cell death in the cultures was determined by trypan blue as described by Tollefson and colleagues [25]. Error bars represent the SD (n = 3) * - statistical significance; unpaired, two sided t-test, p < 0.01. ♦ - wtHAdV-5 infected and ▲ - RL-07 infected.
