We're looking at the custom synthesis for MT-2, and the specs are pretty straightforward — >99% purity by HPLC, white powder, soluble in water, and the sequence is Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2 with a molecular weight of 1024.2 g/mol, which is standerd for this peptide.
Storage is critical here, -20°C and protected form light, or you'll see degradation within a few weeks — we usually have stock, but confirm lead time if you need it faster than 20 days or so.
It's not suited for anything in vivo or clinical work, obviously, since this is research use only, and most buyers go with the 10mg vial for initial studies, but if you're running larger assays, teh 50mg pack is more economical per milligram.
COA from our GMP and ISO 9001 facility will include the actual HPLC trace and mass spec data, and our company can provide a sample for qualified researchers if you need to validate purity before committing to a full batch.
What it does is stimulate melanin production without UV exposure, so it's useful for pigmentation pathway studies, but honestly, if you're working with cell lines that don't express MC1R, it won't do much — that's a common oversight.
Anyway, we're quoting base on the 100mg custom synthesis with a 2-week lead time, and the MOQ for this grade is typically 50mg or 100mg depending on your batch size — let me know if you need the SDS and TDS sent over.
We can start with as little as 100 mg for qualified research labs, but larger batches are available—just let us know your required amount.
For standard purity and quantity, expect 2-3 weeks after order confirmation. Rush options can cut that down, depending on your volume.
Yes, we include both GMP and ISO 9001 certificates, plus a detailed COA showing >99% purity by HPLC. Just request any specific docs you need.
Absolutely—we offer full custom synthesis. If you need a modified sequence, different protecting groups, or a label like a fluorescent tag, send us the specs.
Keep it at -20°C, protected from light. Under those conditions, the powder is stable for at least 12 months. Once dissolved in water, use it within a few days.
