Fig. 2From: Fipronil disturbs the antigen-specific immune responses and GABAergic gene expression in the ovalbumin-immunized BALB/c miceInduction of OVA-specific IgG1 and IgG2a production in vivo. The serum levels of OVA-specific IgM, IgG1, and IgG2a were determined by ELISA. Data was expressed as mean ± SEM of 20 individuals pooled from 4 independent experiments. *p < 0.05 as compared with the VH groupBack to article page
