Ordering Information

Biological Activity

Bremelanotide Acetate is a synthetic peptide melanocortin receptor agonist that targets melanocortin-3 and melanocortin-4 receptors. Activation of central melanocortin receptor signaling stimulates intracellular cyclic AMP accumulation within target central nervous system neurons. This downstream pathway modulation promotes neural responses governing sexual motivation and appetitive behavior, leading to increased lordosis and solicitous responses in preclinical models. [1]

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).
