Someone running a GLP-1 receptor binding assay on a tight timeline typically needs a peptide they can reconstitute fast—that's where having a lyophilized batch at 99% purity makes a real difference, because you’re not wasting time chasing impurities or dealing with solubility quirks that can throw off your.
The molecular weight runs about 4813 g/mol with that C225H348N48O68 formula, and the CAS is 2023788-19-2, so it’s the exact same structure you’d expect for LY3298176—basically the pharmaceutical-grade stuff we’ve handled for a few years now, usually in stock at 5mg or 10mg per vial depending on what your lab typically orders.
We’ve seen most buyers use this for in vitro metabolic pathway studies, but it’s actually not ideal for oral bioavailability work since peptides degrade badly in the gut—that’s just the biology of it, no way around that limitation (check the literature if you’re new to this applicaion).
10 vials come per kit in a lyophilized powder form, and we store them cool and dry away form light, so stability holds up for about six months or so in teh fridge if you keep it sealed.
One thing someone might not think to ask is that the COA typically includes HPLC traces for batch-to-batch consistency—we don’t always volunteer that upfront, but it’s avaliable when you request it.
Anyway, ordering’s straightforward with MOQs typically at one kit, though bulk discounts kick in around 5 kits or more—just let us know the vial size you need.
We sell by the kit—10 vials per kit. You can order a single kit if you want, but bulk discounts kick in at 5 kits or more.
Stock orders usually ship within 2-3 business days. If you need a custom batch or larger volume, add about 7-10 days for production.
Yes, every order comes with a COA confirming 99% purity by HPLC. We can also share third-party test results on request.
Our standard sizes are 5mg to 30mg per vial, but we can do custom fills for larger orders—just let us know the quantity and we'll quote you.
Keep it in a cool, dry place away from light and moisture. Once reconstituted, use it right away unless you're storing it short-term at 2-8°C.
