Figure 5From: Efficient production of chimeric Human papillomavirus 16 L1 protein bearing the M2e influenza epitope in Nicotiana benthamiana plantsCharacterization of L1ΔC22 and chimeric variants expressed in N. benthamiana by capture-ELISA using linear and conformation-specific MAbs. HPV-16 L1 VLPs derived from insect-cells were used as standard of known concentration (0.4 ng/μl). Absorbance values refer to 2 h after substrate addition.Back to article page
