Ovalbumin food allergy model:

The OVA food allergy model has been described previously( 16 , 24 ). Briefly, 6-week-old conventional female BALB/c OlaHsd mice (10–15 animals per group) (Harlan Laboratories) were sensitised via the oral route daily during the first 3 d and then at weekly intervals with 20 mg of OVA (Sigma) along with 10 μg/mouse of cholera toxin used as an adjuvant (List Biological Laboratories) for a continuous period of 7 weeks. …

Analysis of T-cell and monocyte population activation:

…Monocyte populations in the PBMC samples (200 l per well) were stimulated in separate ninety-six-well plates with 10 g/l of ultra-pure lipopolysaccharide (LPS; List Biological Laboratories, Inc.) per well or an equal volume of sterile endotoxin-free water as a negative control. PBMC were incubated at 37°C in 5 % CO₂ and the supernatants were removed after 24, 48 and 72 h for the analysis of monocyte-derived cytokines as described below.

SNAPtide Assay[44]

Recombinant 425aa BoNT/A LC was used throughout all assays and was prepared as previously described.[45] All SNAPtide assays were run in 40 mM HEPES + 0.1% Triton X-100 at pH 7.4. BoNT/A LC concentrations were 18.5 nM while SNAPtide (prod. no. 521, List Labs) concentrations were 5 M. Fluorescence was recorded continuously for 1.5 h to calculate an accurate k_obs using equation 1. In the preincubation experiments, inhibitors at the specified concentrations were incubated with 925 nM enzyme and diluted 50-fold into substrate and initial rates of SNAPtide cleavage were measured. …
