You’re running a study on water balance regulation and need stable vasopressin analogue that won’t degrade halfway through your assay. What you actually want is something that holds up long enough to get clean data on receptor binding or downstream signaling — and synthetic modifications here deliver exactly that. The 1-deamino and D-Arg8 substitutions aren’t just techncial specs; they basically give this peptide a longer half-life and more consistent activity compared to the natural hormone, which can be frustratingly unstable in solution.
it come as a at ≥99% purity by HPLC, with a molecular weight of 1069.22 g/mol and teh sequence Mpr-Tyr-Phe-Gln-Asn-Cys-Pro-DArg-Gly-NH2 — that’s the exact structure for DDAVP. Slightly soluble in water, so you’ll want to reconstitute carefully and store at 2-8°C afterward. We typically have MOQs starting at 5mg or 10mg depending on what you need, and COAs are availble on request. The CAS is 16679-58-6 if you’re checking it against your inventory.
People use this a lot for central diabetes insipidus mechanisms, nocturnal enuresis research, and coagulation factor VIII studies — but it’s research grade only, so don’t expect it to work in clinical or veterinary settings. A thing most buyers don’t think to ask: after reconstitution, it’s stable for about 20 days or so under proper refrigeration, but we usually say 2-4 weeks is a safe window. Also, it’s not ideal for long-term aqueous experiments without buffering — the solubility is limited, so plan your dilutions accordingly.
Anyway, ordering is straightforward — we ship lyophilized, usually within 48 hours if stock is confirmed, though confirm lead time for larger batches. You’ll get the powder in a vial, ready to weigh out.
We can do as little as 1 gram for research orders, but larger quantities usually come with better pricing. Just let us know how much you need.
Yes, every batch comes with a CoA showing HPLC purity ≥99%, molecular weight confirmation, and appearance. We can also share the HPLC chromatogram if requested.
Keep it at 2-8°C after reconstitution to maintain stability. The lyophilized powder is stable at room temperature for short periods, but refrigeration is best long-term.
It's only slightly soluble in water, so don't expect it to dissolve easily in plain water. For research, we recommend using a small amount of DMSO or acetic acid first, then diluting with buffer.
For stock items, we usually ship within 3-5 business days. Custom quantities might take a bit longer, but we'll confirm exact timing when you place the order.
Rapid shipping was the first thing that impressed me—the package arrived two days ahead of schedule, securely packed with temperature-sensitive materials to ensure product integrity. Regarding quality, the lyophilized powder appeared uniform and well-sealed, with clear labeling that matched the product description for research use. Customer service was equally commendable; they responded promptly to my inquiry about storage guidelines, providing detailed advice that demonstrated their expertise. Overall, a seamless experience from order to delivery, making this supplier a reliable choice for laboratory needs.
