Fig. 4From: Efficient self-assembly and protective efficacy of infectious bursal disease virus-like particles by a recombinant baculovirus co-expressing precursor polyprotein and VP4Correlation between recombinant VLP antigen reactivity and IBDV antigen reactivity. Linear regression of the mean S/P ratios obtained from the absorbance values of the reactivity of anti-VP2 MAb to wild type parental IBDV (LC10) and recombinant VLP antigen. The solid line represents the line of best fitBack to article page
