Has a molecular weight just under 5kDa, which puts it in a sweet spot for receptor binding studies—the dual agonism at GLP-1 and GIP sites is what sets it apart from single-target peptides like semaglutide. Purity hits ≥99% by HPLC, and we actually run a second QC pass to confirm that number isn't just a peak pick from a single run. You'll see the COA with the shipment; it's usually included in the box, but confirm if you need it emailed ahead.
The is what you'd expect, but what you might not think to check is residual moisture content after lyophilization—ours runs below 2%, which keeps the cake stable during shiping. Most buyers go with the 10mg vial for standard, though the 5mg is better if you're testing multiple analogs in parallel. Storage at -20°C is non-negotiable; we've seen degradation within 3 weeks if left at room temp, especially after reconstitution. Solubility in water is straightforward, but we recommend sterile water for injection (WFI) rather than saline to avoid salt interference in your assays.
24 months shelf life when stored properly, but that assumes you're not opening the vial repeatedly—once reconstituted, it's good for about 14 days at 4°C if you're careful with aseptic technique. We usually have stock on the 10mg size, but the 15mg and 20mg vials might need a 2-week lead time depending on the synthesis queue.
It's not suited for oral gavage studies in rodents—the peptide's bioavailability is zero through the GI tract, so stick to subcutaneous or intraperitoneal routes for in vivo work. The CAS number (2381089-83-2) is specific to the pure peptide, not any salt form, so you won't get variability from counterion content like you might with acetate salts from some suppilers.
One detail that catches people off guard: the powder can be slightly hygroscopic after opening, so we recommend purging the vial with argon or nitrogen before resealing if you're not using the full amount immediately. Anyway, the documentation includes teh HPLC trace and mass spec confirmation—no hidden peaks above 1% area, which is better than reagent grade from most catalog houses. The MOQ is 5 vials for the 10mg, but our company can do single vials for existing customers.
Our MOQ is typically 10 vials per batch, but we can adjust for larger research projects. Just contact us if you need a different quantity.
Yes, we include a COA with every order that confirms the ≥99% HPLC purity and other specs. It's available upon request before or after shipment.
Keep it at -20°C in a freezer, away from moisture and light. Once reconstituted, use it within a few days and avoid repeated freeze-thaw cycles.
We can customize vial sizes for larger research volumes, but it usually requires a minimum batch order. Let us know your needs, and we'll work out the details.
Standard orders ship within 3-5 business days after payment confirmation. Expedited shipping is available if you need it faster.
