Ordering Information

Biological Activity

Toltrazuril is an antiprotozoal triazinone agent with broad-spectrum activity against intracellular Coccidia parasites. It impairs parasitic mitochondrial respiratory chain enzymatic activities and disrupts schizogony and gametogony developmental stages. This pharmacological inhibition causes ultrastructural damage including cellular swelling of the endoplasmic reticulum and Golgi complex, ultimately disrupting pyrimidine synthesis, nuclear division, and intracellular parasite survival.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
