Fig. 4: The recombinant 6x-His-tagged proteins were successfully loaded onto chitosan-pectin nanoparticles.

The morphological characterization of the nanoparticles was evaluated by Transmission Electron Microscopy. Micrographs of the prepared: A CS:P NPs, B Non-specific antigen control BSA-CS:P NPs, C 6x-His-LY-CS:P NPs, D 6x-His-KT-CS:P NPs, and E 6x-His-BD-CS:P NPs were taken using a JEOL 2010 Transmission Electron Microscope. Bar indicates 200 nm. CS:P chitosan-pectin, BSA Bovine serum albumin.
