PLGA nanoparticles with gp100:272-300 long peptide and Atto488 coated with αCLEC9A or RbIgG via protein A were characterized by DLS and ζ potential measurements. Nanoparticles diameter data represent the mean value ± SD and the polydispersity index as measured by DLS. Zeta potential data represent the mean value ± SD of five readings. Loading efficiency of gp100:272-300 long peptide was measured by Coomassie dye protein assay. The conjugation efficiency of αCLEC9A and RbIgG was determined by Coomassie dye protein assay.
PLGA indicates poly(lactic-co-glycolic acid).
