Basically, we've seen this peptide used mostly in tanning studies—it stimulates melanin production pretty directly, so researchers use it to model pigmentation pathways in vitro or in vivo, depending on your setup.
CAS is 121062-08-6, molecular weight 1024.18 g/mol, and purity runs ≥99% by HPLC, which is tighter than what most reagent-grade suppliers offer; you'll get a, soluble in water at about 1 mg/ml, and peptide content is >95% (usually a bit higher, but we state the floor).
Handling it requires standerd PPE—gloves, goggles, lab coat—and storage at 2-8°C, protected form light, otherwise it degrades faster than you'd think; 3 months in a fridge is no problem if sealed, but we usually have stock so confirm lead time (usually 20 days or so).
It's not ideal for anything beyond research use, obviously—no human use, no cosmetic compounding—but a bunch of buyers use it for melanocortin receptor binding assays, not just tanning, and the 5 mg vials are easier to reconstitute than bulk drums.
We ship with a COA and HPLC trace, though some clients ask for a third-party test which our company can arrange at cost; one thing most people don't ask about is that teh powder can clump if exposed to moisture, so keep desiccant in the container.
We typically require a minimum order of 1 gram for this product, but we can discuss smaller quantities for research purposes if needed.
Yes, we include a COA with every batch, showing HPLC purity ≥99% and peptide content >95%. Just request it when you place your order.
Store it at 2-8°C in a refrigerator, protected from light. It's a lyophilized powder, so keep it sealed and dry. Proper storage ensures the high purity holds up.
Sure, we can pack it in custom sizes like 5g or 10g vials. Just let us know your preferred quantity, and we'll adjust the packaging accordingly.
Yes, it's soluble in water at 1 mg/ml as specified. Use sterile water and avoid vigorous shaking to prevent foaming. Handle it in a lab setting only.
