Analysis of the IgG antibody subclasses elicited by NLP-4S and NLP-4S-PBS57. 4S was used as the coating antigen. Each data reflects an average of three measurements using pooled sera from the NLP-4S and NLP-4S-PBS57 groups (Day 39) and goat anti-mouse IgG1, IgG2b, IgG2c and IgG3 antibodies. Error bars represent the standard error. Statistical differences were determined by two-tailed unpaired t test analysis and is indicated as non-significant (ns) or *0.01 < P < 0.05
