Figure Lengend Snippet: (a) HepG2 liver cancer cell uptake of PEGylated asymmetric anti-glypican-3 immunoliposomes. (b) CV-1 monkey kidney cell uptake of PEGylated asymmetric anti-glypican-3 immunoliposomes. In both cases, cells were incubated overnight with FBS and antibiotic free media in the presence of asymmetric immunoliposomes encapsulating Alexa Fluor 555 hydrazide salt and eGFP plasmid. Cells were rinsed and stained with Hoechst 33342 to illuminate the nuclei and FITC-tagged detection antibodies complementary to anti-glypican-3 and human IgG to illuminate non-internalized immunoliposomes. Images were taken 5 days after immunoliposome addition. Any fluorescence crossover between the images was systematically removed. HepG2 cells show internalization of liposomes, however eGFP expression doesn’t occur. Image of External IgG-conjugated liposomes not shown.
Article Snippet: Human serum IgG (#14506) was from Sigma-Aldrich, rabbit glypican-3 antibody (#sc-11395) and FITC labeled goat anti-rabbit IgG (#sc-2012) was from Santa Cruz Biotechnology, and Cy3 labeled goat anti-human IgG (#109095003) was obtained from Jackson Immunology.
