Arsenic inhibits RBL-2H3 cell degranulation following 1 hour exposure to DNP-BSA antigen (Ag). Effects of various concentrations of As on 1 hour, 0.00016 μg mL-1Ag-mediated degranulation were assessed as described (Hutchinson et al., 2011). In the absence of As, this antigen dose elicited an average absolute degranulation response of 12 ± 2% (SEM; ∼23% of the maximal response). Values represent means ± SEM for five independent experiments, where three replicates per dose were performed for each experiment. One-way ANOVA with Tukey's post-tests (compared to the 1 ppb sample) were performed using Graphpad Prism software; *p< 0.05, ***p< 0.001.
