Figure 5. Characteristics and uptake efficiency of Td carrying ASOs. a) A sketch of Td-O and Td-L and the formation of Td-O and Td-L verified by agarose gel. b) The hydrodynamic size of Td-O and Td-L determined by DLS analysis. c) Flow cytometry analysis of the uptake efficiency of LP-Td-O and LP-Td-L by E. coli and S. aureus . The bacterial cells were incubated with 0.5 μM FAM-labeled LP-Td-L or LP-TD-O for 1.5 h and then assessed by flow cytometry. LP: LP2000.
