Placental macrophage and THP-1 cell treatment:

… For COX-2 selective inhibition experiments, cells were pretreated with 1 M NS-398 for 30 min, and then treated for 24 h with solvent control or 180 M MEHP with or without 1 M NS-398. Effective inhibitor concentrations were identified based on preliminary concentration response curves in THP-1 cells, using 500 ng/mL LPS as an inducer of COX-2 (data not shown). …

Materials for Experiments:

BoNT/A LC and HC were purchased from List Biological Laboratories inc. …

Biotinylation of BoNT/A HC and BoNT/A LC

BoNT/A LC (30 g) and BoNT/A HC (50 g) were biotinylated using the ChromaLinkBiotin One-Shot Antibody Labeling Kit according to Solulinks instructions. Two parameters were necessary to determine the concentration of the proteins: the mass extinction coefficient (E1%) for BoNT/A HC and LC, and their absorbance at 280 nm. The E1% of BoNT/A HC was reported to be 17.1 by Weatherly, G. T. et al [22]. E1% value of BoNT/A LC was roughly estimated to be 10. The biotin molar substitution ratio of biotinylated BoNT/A LC and biotinylated BoNT/A HC was calculated to be 2 and 4.3, respectively, using the MSR calculator of Solulink. The total biotin-labeled BoNT/A HC recovered after biotinylation was 28.3 g and the total labeled BoNT/A LC was 43.9 g. …
