Figure 3. Cellular uptake of albumin nanoparticle is inhibited by low temperature, excess free albumin, filipin, and chlorpromazine

Cellular uptake of h uman serum albumin nanoparticles (HSA NP; 0.1 mg/ml) in 1 h at 37 °C in the absence or presence of filipin (1 μg/ml), chlorpromazine (50 μM), or free HSA (20, 10 and 5 mg/ml), and at 4 °C (Data are presented as mean±SD), n=9. * and ** indicate significant difference from the control group at p less than or equal to 0.05, and p less than or equal to 0.01, respectively.
