document: indeed conjugated on the surface of Qβ@b-3WJsiEGFR siLUC. The results were also confirmed by SDS-PAGE, new bands appeared at 17.1 kDa (single TAT peptide conjugation on one Qβ capsid protein monomer) and 19.8 kDa (two TAT peptides conjugated on one Qβ capsid protein monomer) after TAT peptide conjugation (Figure 3f, Lane 2) compared with non-modified Qβ@b-3WJsiEGFR siLUC (Figure 3f, Lane 1), thereby proving the successful conjugation of TAT peptides on Qβ@b-3WJsiEGFR siLUC to form
