Inhibitory effect and neutralizing ability of the RCmAb 1G8 against NA. a Inhibition of NA activity measured via ELLA. RCmAb 1G8 was diluted from 2^− 1 to 2^− 10and incubated with X1 virus. Purified mAb 1G8 at initial concentration of 20 µg/mL was used as positive control. The supernatant of COS-1 cells transfected with pCAGGS was used as negative control. b HA titer and c TCID₅₀ of X1 virus in MN assay incubated with RCmAb 1G8. mAb 1G8 at concentration of 5 µg/mL was used as positive control. The supernatant of COS-1 cells transfected with pCAGGS was used as negative control
