So you're sourcing a GLP-1 agonist and tired of chasing purity claims that don't hold up under HPLC—this one comes in at >99% with endotoxins under 5 EU/mg, which basically means you're not fighting inflammatory responses in your assays, and the 3751.2 g/mol molecular weight is consistent batch to batch when stored properly at 2-8°C.
We've seen labs push this into weight loss studies and diabetes models alike, and what it does is mimic GLP-1 binding without the rapid degradation you'd get form endogenous peptide—the His-Ala-Glu-Gly sequence at the N-terminus is what gives it that 13-hour half-life or so, but don't expect miracles if your cell line lacks GLP-1 receptor expression (check your transfection first).
Most buyers go with the 10mg/vial for smaller in vivo work—the reconstitutes clean in water, and we've had no complaints about solubility issues even at higher concentrations, though the 50mg/vial format is better suited for chronic dosing studies where you're running multiple cohorts over 4-6 weeks.
Actually, the sterility filtration step is something we do in-house, so you're getting <0.5% impurities and <10 ppm heavy metals without needing to re-filter—just reconstitute and use within 24 hours if you're keeping it at room temp, but we usually have stock ready to ship within 20 days or so (confirm lead time for custom vial sizes).
Anyway, peptide content sits above 95%, and the water content under 5% means you're not paying for freeze-dried fluff—just don't use this for acute toxicity screens where you'd need a shorter-acting agonist, because teh slow gastric emptying effect can skew your metabolic data.
Residual solvents meet ICH guidelines, so you're clear for most regulatory submissions, and we've found the 24-month shelf life holds up even in less-than-ideal fridge conditions—one detail buyers miss is that repeated freeze-thaw cycles degrade the tertiary structure faster than you'd expect.
We can start with as low as 10 vials per order for the 10mg/vial size, but larger quantities get better pricing. Custom packaging is also available if you need a different vial size.
Yes, we include a Certificate of Analysis with each batch that shows the >99% HPLC purity, endotoxin levels under 5 EU/mg, and other specs like heavy metals and residual solvents.
For that quantity, lead time is usually 7-10 business days after order confirmation. If you need it faster, we can sometimes expedite for an additional fee.
Keep the powder at 2-8°C in a refrigerator, and after reconstitution, use it immediately or store the solution at 2-8°C for up to 24 hours. Avoid freezing or exposing to light.
Absolutely, we can customize the vial fill to any amount you need within that range—just let us know the exact dosage per vial when you place the order.
