Ordering Information

Biological Activity

Reserpine is an indole alkaloid that acts as a potent inhibitor of vesicular monoamine transporters, particularly VMAT2, as well as multidrug efflux pumps. By blocking vesicular monoamine transport, reserpine prevents the storage of norepinephrine, serotonin, and dopamine in presynaptic vesicles, leaving them vulnerable to enzymatic degradation by monoamine oxidase. This vesicular depletion impairs monoaminergic neurotransmission and can be utilized to induce experimental animal models of gastric and intestinal ulcers. [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).
