We’ve been running this batch through our standdard receptor-binding assays, and the dual GIP/GLP-1 activation profile holds up consistently—better than the single-target analogs we tested last quarter. Most buyers go with the 10mg vial for initial dose-response work, though the 5mg is easier to handle if you’re just confirming the mechanism. It basically saves us from having to titrate two separate peptides.
The lyophilized powder reconstitutes cleanly in sterile water or PBS, but we’ve found it’s not suited for long-term storage above -20°C—degradation kicks in after about 30 days at 4°C. Molecular weight is 4813.45 g/mol, and teh CAS is 2023788-19-2, but what actually matters is the HPLC purity stays above 98% batch to batch. We usually have COAs on hand, though confirm lead time if you need them expedited.
One detail a buyer might not think to ask: the peptide is hygroscopic, so we always open vials in a dry glove box or under argon. We’ve had a few labs skip that step and end up with clumpy powder—it still works, but reconstitution takes longer. The shelf life is over 2 years if stored at -20°C, give or take a few months depending on freeze-thaw cycles.
Also, we typically stock it in 2mg, 5mg, and 10mg formats, but the 50mg bulk vial is available on request—MOQ is usually 10 vials for that size. The white powder appearance is consistent across all lots we’ve received, which is a minor but reassuring sign of process control. We’ve had no complaints about solubility or aggregation in standard assays we run.
For practical sourcing, we order through a distributor who requires a signed research-use-only agreement—no exceptions. Lead time is about 2-3 weeks form order to dilevery, though we’ve had one batch arrive in 10 days. The packging is a sealed glass vial with a rubber stopper and aluminum crimp, nothing fancy, but it holds vacuum well.
We can do as little as 1 gram for research orders, but larger quantities are available. Just let us know how much you need and we'll work out the pricing.
Standard orders ship within 3-5 business days after payment clears. If you need it faster, we can arrange rush shipping for an extra fee.
Yes, we include a COA with HPLC purity data showing >98% purity for every batch. Just request it with your order and we'll send it along.
Keep it at -20°C for long-term storage—that's a standard freezer temp. Properly stored, it stays stable for over 2 years, as stated in the specs.
Absolutely, we can customize packaging sizes or add your lab's label for bulk orders. Just specify your requirements when placing the order.
