Fig. 10 — Intracellular uptake of OFH-LPH in Human lung fibroblast (CCD-19Lu) Cells by flow cytometry. Cells were incubated with DiI-labelled OFH-LPH at 50 nM for 4 h (green) or 24 h (blue). Flow cytometry histogram for the uptake of DiI-labelled OFH-LPH (A). Cellular uptake was quantified by mean fluorescence intensity (MFI) using flow cytometry and FL-2 detector (B). LPH uptake was intensified in a time-dependent manner. Data points represent mean and SD (n = 3). Statistical analysis was carried out using one-way ANOVA followed by the Tukey HSD test and P < 0.05 was considered significant.
