Comes as a in sealed vials, and we've been making this decapeptide for years now—teh sequence runs pGlu-Gln-Asp-Tyr(SO3H)-Thr-Gly-Trp-Met-Asp-Phe-NH2, which is a pretty potent cholecystokinin receptor agonist for digestive research.
It's not great for oral dosing though given its slight water solubility, but for injected or perfused models it works well. 1352.40 g/mol molecular weight, CAS 17650-98-5, and we test purity via HPLC (usually holds above 99% min).
Most labs use it to stimulate gallbladder contraction or study pancreatic secretion—basically anything involving gastrointestinal hormone signaling. One thing most buyers don't think to ask is reconstitution shelf life: after mixing, it's typically stable 20 days or so at 2-8°C, but we'd verify timing for your specific buffer.
We run full COAs with each shipment including HPLC traces and mass spec confirmation, and batch consistency is tighter than some suppilers we've seen. Lead time is usually 5-7 business days for stock items, though we recommend checking ahead if you need 50 vials or more.
Also, our company offer a straightforward retest policy on unopened matrial within 30 days—just send it back if purity doesn't match the spec. 10mg or 15mg vials depending on your order, and the 10mg size is what most researchers grab first.
