Transduction and binding on sialic acid-deficient cell lines. (A) Transduction of CHO cells (Pro-5) and sialic acid-deficient CHO cells (Lec-2) with AAV1, AAV6, and AAV2. RLU, relative light units. (B) Binding of AAV1, AAV6, and AAV2 to Pro-5 cells and Lec-2 cells. Values are means from three experiments. Error bars represent standard deviations.
