You're looking at a 39-amino acid polypeptide with a molecular weight just shy of 4813 g/mol, CAS 2023788-19-2, and it's a dual GIP and GLP-1 receptor agonist — basically, it activates two incretin pathways simultaneously, which is what sets it apart form single-target compounds like semaglutide. Purity runs above 99% by HPLC, and we typically stock it in 2mg, 5mg, 10mg, or 15mg per vial depending on your assay scale.
Most buyers in this space are running in-vitro binding studies or on pancreatic beta-cell lines, though some use it for animal model work on glucose tolerance or energy expenditure. It's not suited for human use — that's a hard line — and the lyophilized cake reconstitutes best with sterile water or PBS at pH 7.4, give or take 0.2 pH units. We've seen labs push it to 1mM stock solutions without precipitation, but you'll want to aliquot quickly to avoid freeze-thaw cycles.
The stability profile is actually pretty good at -20°C for 12 months or so, but once reconstituted you're looking at maybe 7-14 days refrigerated before activity drops noticeably. One thing people don't always ask about is the residual moisture content in the lyophilized cake — we target under 3%, and it makes a difference in how cleanly it dissolves. Anyway, the COA covers both purity and moisture, so you'll have that data before shipment.
Supply lead time is typically 5-7 business days for standard vial quantities, but if you need 100+ vials we usually have stock, though confirm lead time for custom fill sizes. The 10mg vial is the most common order — most buyers go with that for routine screening because of that it balances cost per assay with waste reduction. We don't offer bulk kilos in this form; it's really a research-grade material, not a production intermediate.
Also, the EC number is 200-001-8 if you're cataloging it for your lab inventory system, and the alternative name LY3298176 still shows up in older literature. You'll get a hard copy SDS with the shipment, but teh TDS is available as a PDF on request. That's pretty much it for the standdard offering — no custom salt forms, no pre-reconstituted solutions, just the lyophilized powder at 99%+ purity.
Our MOQ is typically 10 vials, but we can discuss smaller orders depending on your research needs. Just reach out to confirm.
Standard lead time is 3-5 business days after order confirmation. Express shipping options are available if you need it faster.
Yes, each batch comes with a COA showing HPLC purity data. We can also share third-party test results upon request.
We offer 2mg, 5mg, 10mg, and 15mg per vial, so the 2mg size is available. Just specify your preferred dosage when ordering.
Keep it sealed in a cool, dry place, ideally at -20°C. Avoid repeated freeze-thaw cycles to preserve the peptide's integrity.
