We’ve been running it through our own HPLC before we even put it in the fridge, and purity checks in at 99% or better across the last three batches—the COA form the suplier shows 99.2% on the last lot, which is tighter than the 98% minimum they quote. Teh molecular weight is 4813.5 g/mol, which matches the C225H348N48O68 structure, and we usually have stock on the 5mg and 10mg vials, but the 15mg and 30mg might need a lead time of 2-3 weeks or so.
Most buyers go with the 5mg or 10mg for their initial dose-response work, and it’s not really suited for anything beyond research application—definitely not for human use. It’s a in sterile vials with rubber stoppers and aluminum seals, and what it does is dissolve readily in sterile water or buffer for reconstitution. And we’ve found the batch-to-batch consistency is solid, especially if you stick with same lot for a full study.
Storage is straightforward—2-8°C short term, and for anything over a month, we recommend -20°C, though we’ve had vials hold stability at -20°C for a full 24 months without degradation. The shelf life is 24 months when properly stored, and we typically retest any lot that sits past 18 months just to be safe.
Actually, one detail that caught me off guard is that the peptide is pretty hygroscopic once reconstituted, so you’ll want to aliquot it quickly and avoid freeze-thaw cycles—most researchers don’t think to ask about that until they’ve lost a vial. Anyway, the CAS is 2023788-19-2, and we’ve got the SDS and retest policy on file if anyone needs it.
For supply, our company can customize the packaging per vial—5mg, 10mg, 15mg, or 30mg—and the MOQ is typically 10 vials for the standerd sizes, but we can do smaller orders for the 5mg if you’re just scoping it out. We usually have stock, but confirm lead time if you need more than 50 units.
We’ve also seen some buyers use this for in vitro binding assays, and it performs better than reagent-grade peptides for that because of the tighter HPLC purity specs—basically, it cuts down on false positives from impurities. The COA comes with every lot, and we can pull a retest sample if you’re concerned about storage conditions during transit.
We can start from as low as 10 vials for a trial order. For larger quantities, we offer volume discounts, so just reach out with your target amount.
Yes, every batch comes with a full COA that includes HPLC purity data, mass spec results, and storage conditions. It’s standard with every shipment.
Absolutely — we offer customizable packaging from 5mg up to 30mg per vial. Just let us know the dosage you need, and we’ll adjust the order accordingly.
For stock sizes, we ship within 3-5 business days. Custom orders or larger volumes may take 7-10 days, depending on the quantity and packaging.
Keep it at -20°C for long-term storage; it stays stable for 24 months that way. For short-term use, 2-8°C is fine — just avoid freeze-thaw cycles.
