• Product #100B – Cholera Toxin (AZIDE-FREE) from Vibrio cholerae

Reagents:

… CTB (choleragenoid, 103B) and Clostridium difficle toxin B (TcdB) (6246-GT-020) were purchased from List Biological Laboratories and R&D Systems, respectively. …

Measurement of IL-1 production in vitro:

For measuring IL-1 production in vitro, 2 10⁵ cells per well in 96-well plates were first cultured for 5 h in the absence or presence of LPS O55:B5 or LPS O111:B4. Then CTB, ATP, R848 or TcdB was added at indicated concentrations and further cultured for indicated hours. A pan-caspase inhibitor, Z-VAD-FMK (4800-520, MBL), and a protein kinase A (PKA) inhibitor, H-89 (10010556, Cayman Chemical), were added 3 h before addition of CTB or ATP. Dimethyl sulfoxide (DMSO, Nacalai Tesque) was used as a solvent control for inhibitors. …

Measurement of IL-1 production in vivo:

Mice were injected intra-peritoneally (i.p.) with 100 g LPS O55:B5 per head. Five hours later, CTB was injected i.p. at 100 µg per head. PBS was used as a control for CTB. Then further 6 h later, peritoneal lavage fluids were harvested and subjected to ELISA for IL-1.

Assessment of toxin neutralizing antibodies

Toxin neutralization assay was performed as previously described^4,5,6. Briefly, sample dilutions were added to J774 macrophages cultured in cultured in RPMI supplemented with 10% fetal calf serum. Bacillus anthracis lethal toxin (LeTx) [i.e., PA plus Bacillus anthracis lethal factor (LF, List Biological, Campbell, CA)] was then added to the plates. After overnight incubation, MTT (3-(4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide; Sigma-Aldrich) was added to assess the viability of macrophages as a function of redox potential. Toxin neutralizing antibody titers were determined as the lowest concentrations of sera  that protect macrophages from the cytotoxicity of LeTx.
