a, Huh-7 cell lysates were incubated with hCoV-EMC and SARS-CoV S1–Fc proteins and affinity-isolated proteins were subjected to protein electrophoresis under non-reducing conditions. The arrowhead indicates the position of the ∼110-kDa DPP4 protein specifically isolated using the hCoV-EMC S1–Fc protein. b, hCoV-EMC and SARS-CoV S1–Fc proteins were mock-incubated or incubated with soluble DPP4 (sDPP4) or soluble ACE2 (sACE2) followed by protein A sepharose affinity isolation and subjected to protein electrophoresis under non-reducing conditions.
