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

Materials:

… Pertussis toxin (PTx) was from List Biological Laboratories (Campbell, CA, USA). …

Degranulation Assay:

The degranulation was measured by -hexosaminidase release as described previously [51]. Briefly, transfected RBL-2H3 cells (5 10⁴ cells per well) were seeded into a 96-well, white, clear-bottom cell culture plate and incubated overnight in a 37 C incubator with 5% CO₂. To determine the inhibitory effects of PTx and YM-254890 on MC degranulation, cells were pretreated with PTx (100 ng/mL, 16 h) and/or YM-254890 (10 M, 5 min) prior to stimulation with SP. Cells were then washed twice and suspended in a total volume of 50 L HEPES buffer containing 0.1% bovine serum albumin (BSA). …

PTX and TCDD Administration:

… Groups of 3–5 mice were first injected IP with vehicle (CO), or TCDD (25 μg/kg body weight) then injected IP with 400 ng/mouse PTX (List Biological Laboratories, Campbell, CA, United States). Twenty-four hour later, the mice were rechallenged with the same dose of PTX intraperitoneally, as described (Elliott et al., 2018).
