Toxin A inhibition assays:

Vero cells (CCL-81; ATCC, Manassas, VA) were maintained in complete media (MEM+antibiotic/antimycotic+10% FBS) in T-75 flasks at 37C, 5% CO₂. For TcdA inhibition assays, sterile 96-well tissue culture plates (Thermo-Fisher, Ottawa, ON, Canada) were seeded with ~210⁴ cells/well in a total volume of 200L of complete media. Plates were incubated for 24h at 37C, 5% CO₂. Media was then carefully removed from each well and replaced with 200L of fresh media, 20L of antibody (serially diluted in sterile PBS, giving final in-well concentrations ranging from 1M to 1.95nM) and 10L of TcdA (List Biological Laboratories; final in-well concentration of 10ng/mL corresponding to 32.5pM) for all wells. …

Cell culture studies:

… For toxin neutralization, we mixed different concentrations of CT (List Biological Laboratories, Campbell, CA) and nanoparticles, incubated for 1 h, and added the mixture to the cell monolayers. After 2 h, supernatants were collected and assayed for cAMP by enzyme immunoassay (Cyclic AMP ELISA Kit, Cayman Chemical Co., Ann Arbor, MI). All cAMP measurements were done without additional acetylation. …
