Identification and characterization of MERS-CoV-RBD-specific Nbs. To construct the Nb (i.e., VHH) library, we immunized llama with recombinant MERS-CoV RBD (residues 377 to 588, EMC2012 strain) containing a C-terminal human IgG1 Fc tag (i.e., RBD-Fc) and isolated peripheral blood mononuclear cells (PBMCs) from the immunized llama. To examine of the role of the D539A mutation in DPP4 binding, we carried out an ELISA to detect the binding between DPP4 and The plates were coated with RBD-Fd protein (2 g/ml) and treated with or without DTT, followed by sequential incubation with serial dilutions of NbMS10 or NbMS10-Fc and goat anti-llama and HRP-conjugated anti-goat IgG antibodies. ./cache/cord-347587-auook38y.txt ./txt/cord-347587-auook38y.txt
