mass confirms the macromolecular synthesis—4113.6 g/mol means you’re working with a long chain that requires careful handling during reconstitution, and we typically see better solubility if you let it sit at 2-8°C for about 10 minutes after adding water.
Actually, we’ve found that the 10mg per vial format is what most buyers go with for dose-response work, though some labs prefer the 10-vial kit to avoid repeated freeze-thaw cycles. It’s a white to off-white powder, pretty much what you’d expect form a ≥99% pure peptide, but what catches people off guard is that even trace moisture can shift teh solubility profile. So if your vial sticks slightly or clumps, it’s probably been exposed—check the COA lot number against your storage log. The CAS 2023788-19-2 matches the synthetic analog, not the human GLP-1, so don’t expect identical pharmacokinetics in your model.
We usually have stock, but confirm lead time if you need more than 20 kits—production batches run every 30 days or so, and we hold roughly 500 vials at any given point. Protected from light in the fridge is non-negotiable; leave it on the bench overnight and you’ll see a measurable purity drop by HPLC the next morning.
One detail that’s easy to miss: the lyophilized cake can be harder to dissolve than you’d think for a peptide labeled water-soluble, so we recommend 0.5 mL of sterile water per vial and gentle swirling, not vortexing. That’s a concrete thing someone who’s handled it would tell you—don’t expect it to clear in 2 seconds like a simple salt. Also, this grade is better than reagent grade for receptor binding studies but not suited for in vivo work unless you’ve got your own purification step after reconstitution.
It basically binds the GLP-1 receptor and drives glucose-dependent insulin secretion while suppressing glucagon—classic GLP-1R agonist behavior. But here’s where experience kicks in: the stability in solution drops after 72 hours at 4°C, so aliquot early if you’re running a long assay series.
We can work with a single kit (10 vials) as the minimum order, but if you need less, just ask — we sometimes split for research labs on a case-by-case basis.
Yes, every batch comes with a COA from our in-house lab showing the actual purity results, typically 99% or higher. We can also send third-party testing reports upon request.
Keep them at 2-8°C in a fridge, tightly sealed and protected from light. Do not freeze. Under these conditions, the powder stays stable for at least 12 months.
Each vial is vacuum-sealed with a desiccant inside the kit, and we ship with ice packs in insulated boxes to keep the temperature stable during transit.
Custom packaging is possible for larger volume orders — we can repack into different vial sizes or kit counts. Just let us know what you need and we'll quote accordingly.
