Fig. 7From: From strain engineering to process development: monoclonal antibody production with an unnatural amino acid in Pichia pastorisSize-exclusion chromatography elution profiles after protein A affinity purification. a IgGpAzF and b IgG sample. Integrated peaks were analyzed by SDS-PAGE with silver staining and western blot and pooled. Numbers above the peaks are areas below the curve relative to the area of the peak corresponding to full-length IgGBack to article page
