Immunological profile of a Plasmodium vivax AMA-1 N-terminus peptide-carbon nanotube conjugate in an infected Plasmodium berghei mouse model
We have covalently conjugated an N-terminus Plasmodium vivax apical membrane antigen-1 (AMA-1) peptide to functionalized carbon nanotubes (f-CNT). Immunological characterization of this molecular conjugate revealed that the immunogen-AMA-1 peptide was appropriately presented after being conjugated t...
