That molecular weight of 2178.6 g/mol means it’s a fairly large peptide, and we’ve found it holds up well in solution if you reconstitute it fresh—most researchers go with water for that, and it dissolves cleanly without much fuss, though we usually recommend filtering it through a 0.22-micron membrane just to be safe.
We’ve been supplying this for a couple of years now, and the 99% purity is pretty consistent batch to batch—HPLC analysis comes with every lot, and we can also provide MS data if you need it, but honestly, the main thing buyers check is the CAS number (1627580-64-6) to match it to their protocols.
It’s not really suited for long-term storage at room tempearture if you’re in a humid climate—keep it away from light and in a dry place, and it’ll stay stable for about 12 months or so, but we’ve had some folks report degradation after 18 months even with proper care.
The 10mg per vial is our standard pack size, and that’s typically enough for a few dozen assays depending on your dilution—most buyers go with that unless they’re running high-throughput screens, in which case our company can do custom batch sizes (usually 20mg or 50mg vials) with a lead time of 2-3 weeks.
One thing that catches people off guard is that the peptide sequence isn’t on teh vial label—you’ll find it in techncial documentation we email with the COA, so make sure to check that before you start your metabolic studies, as the sequence can vary slightly between suppilers and that matters for binding assays.
We usually have stock on hand, but if you’re ordering more than 100 vials, just confirm lead time with us first—it’s typically 5-7 business days, though we’ve had occasional delays during peak demand periods like Q4.
We sell by the vial, so you can order as little as a single 10mg vial. If you need bulk quantities, let us know and we can discuss pricing.
Yes, we include the HPLC analysis report with every batch, so you’ll have the purity data in hand. MS analysis is also available if you request it.
Just keep it at room temperature, away from direct light. That’s it—no special refrigeration needed for this one.
Yes, we run sterility testing on each lot, and the results are documented. You can request a copy of the sterility report with your order.
Sure, the peptide sequence is detailed in our technical documentation, which we can share upon request. Just ask when you place your order.
