You’re looking at a synthetic nonapeptide that mimics the natural hormone for studying water reabsorption and vasoconstriction in lab models, and it’s pretty much the standerd for those cardiovascular and renal pathway experiments—most buyers we deal with need it for dose-response work with AVP receptor assays.
The stuff comes as a with a purity of 99% or better, and molecular weight sits at 1084.23 g/mol (CAS 113-79-1), so it’s slightly soluble in water—we usually recommend reconstituting in a small volume of acetic acid or PBS if you’re pushing for full dissolution.
It’s not suited for anything involving live animals or human use, obviously, and we stress that upfront because some researchers mistake it for a therapeutic grade—it’s strictly research grade, with the sequence [Cys-Tyr-Phe-Gln-Asn-Cys]-Pro-Arg-Gly-OH and a tight tolerance on the disulfide bridge formation that actually matters for binding affinity.
Storage is straightforward: keep the powder at -20°C for long-term, but after you reconstitute it, 2-8°C is fine for about a week or so—we usually have stock on hand, but confirm lead time if you need more than 50 mg at once.
One thing buyers don’t always ask about is the residual acetate content form the synthesis step, which can vary slightly between batches and might affect your solubility if you’re working at high concentrations—we include that on teh COA anyway (HPLC and mass spec).
And the MOQ is typically 10 mg for this one, though our company can do smaller amounts if you’re just starting out, but the 5 mg vial is easier to handle for preliminary assays.
