Mean RLU results for serotype transduction in control and vector-inoculated monolayer-cultured cells. (A) Four days after vector inoculation at 1.0×102 GCs/cell in monolayer-cultured synoviocytes and chondrocytes, serotype rAAV2/5 displayed the highest BPC, followed by serotypes rAAV2/2 and rAAV2/1. (B) No difference was detected between cells transduced with CMV or CB promoter-containing vectors. Error bars represent SE (*p<0.1, **p<0.05, ***p<0.01). BPC, bioluminescence per cell; CB, chicken β-actin; CMV, cytomegalovirus; GCs, genome copies; N.S., not significant; RLU, relative light units; SE, standard error.
