Say you're running a chronic study and need consistent peptide across multiple batches—we've been there, so we hold back a retention sample form every single production run, then retest it at 3 months, 6 months, and again at 12 months, which means you can reorder with confidence even if your first batch sat around a while.
It's a white powder that's pretty much indistinguishable from any other batch visually, but what matters is that our HPLC shows 99.9% every time on the COA, and the molecular weight comes in at 403.31 g/mol (give or take 0.5), so you're not chasing a moving target—we also check endotoxin and sterility, but for research use only you don't usually need that unless your protocol demands it.
A lot of buyers use this for metabolic assays or binding studies, but honestly it's not ideal for long-term cell culture at high concentrations because of that it can aggregate if you don't handle reconstitution right—most researchers go with the 10mg per vial and just reconstitute fresh each day, which avoids that headache.
Anyway, we have stock on the 10-vial kits typically within 20 days or so, and we'll email you teh COA and retest policy before shiping—just confirm your MOQ and we're good to go.
We require a minimum of 1 kit, which is 10 vials (10mg each). Larger quantities are available upon request.
Yes, we include a COA with every shipment showing HPLC results confirming 99.9% purity. Third-party testing reports are also available on request.
Store it at -20°C in a freezer. Keep it sealed and away from light to maintain stability. Avoid freeze-thaw cycles.
Standard orders ship within 3-5 business days. Custom labeling or bulk orders may take 7-10 business days.
The vials are single-use only—they come with a rubber stopper and aluminum seal. Once opened, use the contents immediately and discard any leftover.
