Figure 4From: A systematic study of the N-glycosylation sites of HIV-1 envelope protein on infectivity and antibody-mediated neutralizationNeutralization susceptibility of WT FE and PNGS mutants by several known neutralizing MAbs. All data points represent the means and the error bars indicate the standard deviations from the means that were obtained from three independent experiments. Neutralization assays of the pseudovirions produced from WT and mutants were described in Materials and Methods.Back to article page
