Assay for the screening of the small molecule library against APA and ALF:

An analyzing solution consisting of 10 L of the Small molecule-carrying MRnS
and 2,000 L DI water was prepared. Samples containing different concentrations of free
toxin (APA or ALF, 2 pM to 20 nM, in 1X PBS buffer) were prepared and 2 L of each
sample was added to 200 L of the MRnS analyzing solution (Small molecule-MRnS). A
negative control sample was prepared in the same fashion, adding 2 L fresh 1X PBS
buffer instead of toxin (0 M APA or ALF control sample). Magnetic relaxation
measurements were performed every 15 minutes of incubation at room temperature for 1
hour. …

HT29 and Vero cell cytotoxicity assays:

…The plates were incubated for 48 h (37C; 5% CO2) to let monolayers form before addition of C. difficile culture supernatants…. Cell supernatants from isogenic toxin A B mutants were used as negative controls (20). Pure toxin A and toxin B (List Biological Laboratories) were used as positive controls, so that the detection limit of each assay could be determined in terms of the toxin concentration. The detection limit of the HT29 cell cytotoxicity assay was 100 pg/ml toxin A, and the detection limit of the Vero cell cytotoxicity assay was 25 pg/ml toxin B. …
