If someone's running melanocortin receptor binding assays or studying UV-induced DNA damage repair in melanocytes, they'll reconstitute this lyophilized powder in sterile water at typical concentrations of 1-2 mg/mL and dilute form there.
We've got the CAS 121062-08-6 compound at >99% purity by HPLC—the chromatograms are clean, and we usually include the COA with each shipment (check lead time for custom batch documentation).
Storage is a tight window, 2-8°C in a sealed, dry enviroment, and that's not negotiable; the peptide backbone degrades fast above 8°C, especially as a powder with residual moisture picked up from ambient air.
Actually, the 1024.2 g/mol molecular weight means you'll want to account for peptide content when calculating molarity—some lots come with a slight acetate salt residue that shifts the effective mass by 1-2% or so.
It's better than reagent-grade Melanotan II for competitive binding work because the HPLC consistency holds at 99%+ run to run, but we've seen solubility issues in PBS if the pH drops below 5.5, so pre-warm reconstitution buffer to room temp.
Most buyers get the 50 mg vial format for small-scale studies, but samples are availble if you're just testing dissolution or end-capping stability, and we ship samples within 5 business days when in stock.
Our MT2 is >99% pure, verified by HPLC analysis. We can provide the certificate of analysis with your order.
Samples are available for evaluation. For larger orders, MOQ is typically 10 grams, but we can discuss custom quantities.
Store it at 2-8°C in a dry, airtight container. Avoid moisture and heat to keep the powder stable.
Yes, we offer customized packaging for research quantities. Just let us know your preferred size or format.
For samples, we ship within 2-3 days. Bulk orders usually take 5-7 business days, depending on quantity and customization.
