A researcher in Cambridge reconstituting a 5mg vial with sterile water for a 28-day rodent feeding study—they'll want to know the peptide stays stable in solution for about a week at 4°C, but reconstitute fresh for best results, obviously.
We're running at 99% or better by HPLC, and that CAS you've got—910463-68-2—is correct for the acylated form with the C18 fatty diacid chain, which is what gives it that crazy-long half-life compared to native GLP-1.
Storage is pretty straightforward: keep the lyophilized powder at -20°C in the dark, and it'll hold for 12 months or so—moisture is enemy here, so let the vial come to room temp before opening to avoid condensation.
The 10mg vials are teh most popular for chronic dosing models, but we've got 1mg and 2mg if you're just running acute assays or testing solubility—it dissolves in water easily enough, but don't use PBS right away or it might precipitate.
One thing nobody mentions is that the extended half-life makes it unsuitable for acute pulse-chase experiments—basically, you're stuck with a 24-hour washout period between doses, which some researchers find frustrating.
We usually have UK stock for the 5mg and 10mg sizes, but the 1mg vials (check lead time) can sometimes take a few extra days since they're a less common request.
We provide a Certificate of Analysis (CoA) for each batch, confirming the ≥99% purity and identity via HPLC. If you need additional documentation like an MSDS, just ask.
We don’t have a strict MOQ—you can order single vials if that’s what you need. For bulk orders (like 100+ vials), we can offer a discount.
Standard shipping to the UK takes 5-8 business days with full tracking. Express options can get it there in 2-3 days if you need it faster.
We can do custom vial sizes for larger orders—just reach out with your requirement. For small quantities, we stick to the standard 1mg, 2mg, 5mg, and 10mg vials.
Keep it at -20°C in a freezer, away from light and moisture. Once reconstituted, use it within a few days and don’t freeze again.
