ELISA plate was coated by 2019-nCoV NP (cat#E42020T6), 100 µL/cell at 1µg/ml. The indirect ELISA analysis was performed by loading 100 µL per well of BN9 (RED, cat#E42020T14) and N9-m1 (BLUE, cat#E42020T14m1) at various concentrations, respectively. The plate was incubated for 1 hours at 37℃, then washed 5 times. An
