Fig. 3From: Gold nanoparticles stabilize peptide-drug-conjugates for sustained targeted drug delivery to cancer cellsFlow cytometry analysis of P4 and P6 peptides binding to off-target cells. P4- and P6-FITC conjugates were incubated at the indicated concentrations with cells to ascertain the dose-binding response. The data was collected from Becton Dickson FACS Calibur cell analyzer and analyzed with Flow Jo software. Aside from the strong dose–response to A20 target cells P4 binds a small population of NB4 and HL-60 myeloid leukemic cells but not to PBMC or MOPC cellsBack to article page
