What is Alprostadil?
Alprostadil is a synthetic form of Prostaglandin E1 (PGE1). Acts on EP receptors (EP2/EP3/EP4) to stimulate adenylyl cyclase, raise intracellular cAMP, and relax vascular smooth muscle. Studied for penile vascular physiology, peripheral artery disease models, and platelet aggregation inhibition. Research use only.

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2 mL bacteriostatic water to the lyophilized vial. Swirl gently until clear — dissolves readily within 1 minute. Use within 24 hours of reconstitution for best stability.
How should this peptide be stored?
Store lyophilized vials at 2–8°C or −20°C for long-term. Reconstituted solution should be used promptly; stability at 2–8°C is limited to 24–48 hours. PGE1 is susceptible to oxidation.
What purity is this QSC compound and how is it verified?
Alprostadil is a well-characterised PGE1 analogue used in vascular biology, erectile physiology, and platelet research. It enables precise EP receptor activation and cAMP pathway manipulation in smooth muscle and endothelial cell models.
