Biological activities of the recombinant AAT products secreted into BY-2 cell culture media. The medium samples harvested after 10-day of BY-2 cell culture as well as the purified AAT-(AP)20 fusion protein (pAAT-(AP)20) were assayed. The percentage of the active AAT accounting for the total AAT products in the samples was then calculated as: active AAT content/total AAT concentration×100%. The error bars represent the standard deviation of three top-expression cell lines for each gene construct (for the medium samples) or three parallel samples (for the pAAT-(AP)20 protein).
