Ordering Information

Biological Activity

Carbetocin Acetate is a synthetic analogue of oxytocin that acts as a potent agonist of the oxytocin receptor (OXTR). Activation of OXTR by carbetocin stimulates G protein-coupled signaling, promoting downstream intracellular calcium mobilization and uterine smooth muscle contraction. Carbetocin exhibits enhanced metabolic stability relative to native oxytocin, sustaining functional receptor activation.

All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 100 mg/mL (101.19 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
Water 100 mg/mL
Ethanol 100 mg/mL
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).
