Ordering Information

Biological Activity

Oxfendazole is a broad-spectrum benzimidazole anthelmintic agent that targets parasitic β-tubulin. By selectively binding to β-tubulin, oxfendazole inhibits microtubule polymerization, impairing cellular structure, nutrient uptake, and energy metabolism in helminths. This leads to the disruption of mitotic spindle formation and eventual parasite death, exhibiting potent antiparasitic activity against various gastrointestinal nematodes and larval cestodes. [1]

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).
