<p>The cells were pre-incubated with different concentration of anti-27.8R MAbs. Experimental groups were challenged by LCDV at a MOI of 3.0, and the cells without LCDV infection served as control groups. The cells were sampled at 48 h post infection. Error bars represented SD. Data represented the absorbance value at 405 nm (mean ± SD; n = 3) and were compared by Student’s <i>t</i> test. The asterisk represented the statistical significance (<i>p</i> < 0.05) as compared with the control group.</p
