9 percent is good starting point, but at 4813 g/mol the solubility profile matters a lot in practice—that PEG-modified lysine side chain is actually what separates this form other dual agonists in handling.
We've seen most researchers run this through HPLC with a C18 column, usually confirming purity above 99% the first time, though we always include a fresh COA with every 500mg or so batch.
99% is tight enough for subcutaneous dosing studies, and white lyophilized cake reconstitutes cleanly in DPBS if you let it sit for 30 seconds—not what you want for intravenous injection though.
Storage is non-negotiable at minus twenty protected from light, because degradation products show up fast above that, usually within a couple weeks if left out.
What it does is activate both GIP and GLP-1 receptors with roughly equal affinity, but it's the stability of the PEG linker that keeps it active longer than single agonists—basically better than most non-PEGylated options for extended protocols.
CAS 2023788-19-2 is teh one you want for LY3298176, but confirm your synthesis tolerates the PEG chain if you're planning any modifications—most buyers go with 100mg vials for convenience, and lead time is typically under a week.
Our MOQ for this product is typically 1 gram, but we can discuss smaller orders depending on your research needs.
Yes, we include a CoA with every shipment, showing purity ≥99% and confirming all specs like appearance and molecular weight.
Keep it at -20°C, protected from light, in a sealed container. That keeps it stable for long-term research use.
We offer flexible packaging from grams up to bulk quantities. Just let us know your preferred size, and we’ll work it out.
Standard lead time is 5-7 business days after payment confirmation, but we can expedite if you need it sooner.
