Figure 2. Cellular uptake of hairpin-like siRNA-LSNAs.
(A) Hairpin-like siRNA-LSNAs efficiently enter HUVECs in comparison to linear siRNAs, as measured by flow cytometry. Error bars represent the standard deviation of 3 biological replicates. (B) Confocal microscopy images of Cy5-labeled linear siRNAs and hairpin-like siRNA-LSNAs internalized by HUVECs (blue: DAPI stain indicating nucleus, red: Cy5 indicating siRNA), scale bar: 10 μm. Statistical analysis was performed using an unpaired t-test, where “****” represents a P value of <0.0001.
