Structural and nucleic acid binding properties of hepatitis delta virus small antigen

Figure 2 S-HDAg and ∆60HDAg multimerization ability. In panels A and B, purified recombinant protein was cross-linked with increasing concentrations of glutaraldehyde (0%, 0.01% and 0.1%) prior to SDS-PAGE. Proteins were detected by Coomassie blue staining. In panel A, only purified ∆60HDAg was present at 2 μmol/L and in panel B both S-HDAg and ∆60HDAg were present at 2 μmol/L each. The arrow indicates the presence high molecular weight oligomers.
