The biggest thing you need to know upfront is these are non-sterile and research-grade only, so if you're running anything in vivo or clinical, this isn't the materail for you — we've had a few buyers miss that and it's a hard stop.
For standdard in vitro work though, it's actually pretty solid. 3. We routinely batch-test about 50 vials per lot and the HPLC traces come back clean, purity consistently at or above 99% — teh endotoxin level is under 1EU/mg, which is tighter than what some reagent-grade suppilers bother to check.
You'll get a sealed vial with desiccant, lyophilized powder that's water soluble, and we store everything at -20°C (usually 2-4 weeks of stock on hand, but confirm lead time if you need more than 100 units or so). 5. The molecular weight varies by peptide, obviously, and CAS numbers are peptide-specific — our company provide the COA with each batch so you can verify.
One thing that caught me off guard first time: the 12-month stability claim is accurate only if you never let it thaw — we've had a batch degrade in about 8 months after a freezer door was left open, so keep that in mind. 7. Anyway, for most labs running standard assays, the 10mg vial is what we usually go with.
We typically sell in packs of 10 vials per peptide, but for bulk research projects we can often do custom MOQs—just reach out with your volume needs.
Lead time is usually 3-5 business days for standard orders, and yes, each batch comes with its own HPLC report so you can verify the ≥99% purity.
No, they're non-sterile—research grade only. If you need sterile material for cell work, you'll have to filter or reconstitute under sterile conditions yourself.
Yes, every batch is tested and guaranteed <1 EU/mg endotoxin. That's standard for our cGMP facility, and it's included in the specs we provide.
Keep them at -20°C in the sealed vials with the desiccant pack—don't open until you're ready to use. Once reconstituted, they'll degrade faster, so aliquot and freeze if needed.
