From: Enhanced tumor targeting of cRGD peptide-conjugated albumin nanoparticles in the BxPC-3 cell line
Typical flow cytometry plots of the BxPC-3 cells after (a) 4-h incubation with sterile PBS (a), C6-HSA-NPs (b), or C6-cRGD-HSA-NPs (c). The proportion of the purple peak that falls within the M2 range represents the captured C6-positive cells. The lower right column graph shows the mean fluorescence intensity of the cells in the three groups. Data are presented as the mean ± SD (n = 3). These results confirmed that decorating the particle surface with cRGD significantly facilitated the uptake of nanoparticles in the BxPC-3 cells. *p < 0.01, compared with the negative control.
