In parallel, we also produced the recombinant SARS-CoV-2 N protein and its Receptor Binding Domain (RBD) in planta and used them to test the binding specificity of the recombinant mAbs. Finally, for two of the antibodies we assayed a simple scale-up production protocol based on the extraction of apoplastic fluid. Finally, we performed sandwich ELISA tests of sybody17 and nanobody72 ( Fig 5E and Fig 5F, respectively) using the total and concentrated apoplastic fluid as detection reagent against serial dilutions of crude plant extracts from RBD-producing plants, showing that this simple antibody preparation can be directly employed in detection procedures without the need of additional purification steps. ./cache/cord-331786-wgt7kg6f.txt ./txt/cord-331786-wgt7kg6f.txt
