We keep stock of 5mg through 30mg vials, and most buyers go with the 10mg for initial dose-response work — it's basically teh sweet spot for early-stage trials.
Purity runs >99% by HPLC, and what that means for your assays is fewer side peaks messing with binding data; reconstitutes cleanly in sterile water or saline.
Storage is 2-8°C in sealed containers — don't freeze it, and we usually have stock, but confirm lead time if you need more than 50 units or so.
Microbial limits are <10 CFU/g, and our company can run sterility testing on request (usually 2-4 weeks turnaround).
One thing: this isn't suited for in vivo work without proper formulation help — the peptide degrades faster in plasma than some analogs, so plan your pharmacokinetics accordingly.
Also, we prep batches under cGMP with preparative HPLC and SEC, so you'll get a tighter tolerance than reagent grade for binding studies.
There's no set MOQ for the trial sign-up — you can start with as little as a 5mg vial. That said, if you need larger quantities for extended studies, we can scale up from there.
For standard trial sign-ups, we usually ship within 5-7 business days after order confirmation. Custom or bulk requests might take a bit longer, but we'll give you a timeline upfront.
Yes, we can share the HPLC purity report (>99% verified) with every order, and sterility testing is available on request. Just let us know if you need it, and we'll include the documentation.
It's just about the amount of lyophilized powder per vial — both come from the same cGMP-compliant batch with >99% purity. Pick 5mg if you're doing small pilot studies, or go with 30mg if you need more material per vial for larger trials.
Keep it sealed at 2-8°C in your fridge, and avoid moisture. Once reconstituted, use it within a few days and don't freeze the solution. We recommend storing the powder as-is until you're ready to use it.
