Ordering Information

Biological Activity

Ebastine is a potent second-generation histamine H1 receptor antagonist used for studying allergic disorders. By selectively blocking histamine H1 receptors, ebastine prevents histamine-mediated downstream signaling activation, leading to suppressed vascular permeability, reduced mucosal swelling, and inhibited smooth muscle contraction. These actions mitigate acute hypersensitivity reactions and alleviate inflammatory phenotypes associated with allergic responses in preclinical models.

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).
