Schematical diagram of CCMV-CP and NΔ24-CP constructs expressed in E. coli. Six His-tag residues introduced within the predicted loops (βB-βC-His, βD-βE-His, βF-βG-His and βH-βI-His) were cloned as SpeI-SstI, while for the N- and C-terminal end fusion of the CCMV-CP (His-CP, CP-His and His-CP-His) and NΔ24-CP (His-NΔ24-CP and His-HA-NΔ24-CP), the 6xHis-tags were introduced by PCR
