Figure 5. Immunoblots of purified VHH2-Fc antibody from N. benthamiana.

Figure 5

VHH2-Fc antibody was purified twice using Protein G-based chromatography, separated using standard 12% SDS-PAGE under non-reducing (A) and reducing (B) conditions, electrotransferred to PVDF membranes and probed with a polyclonal anti-human IgG (γ-specific) conjugated to AP. Lane 1, molecular weight standard; Lane 2, 100 ng of VHH2-Fc antibody. See text for an explanation of the asterisk.
