If you're running a study that needs consistent dosing across multiple test groups, we can match vial size to your protocol—5mg, 10mg, or 20mg, and we'll even do custom labeling if you need it to keep vials separate, but the lead time on that is usually 2-3 weeks.

99% purity by HPLC is tight enough for most in vitro work, and at 889.02 g/mol it reconstitutes predictably in sterile water or saline, and teh lyophilized cake sits as a white to off-white powder that sticks around for about 2 years if you keep it dry and cool—roughly 4°C is fine, though we've stored it up to 25°C for short periods without issues.

We've seen this used for angiogenesis assays and wound healing models, but it's not for anything involving long-term cell culture unless you're careful with sterilization since it's not gamma-irradiated; also, some buyers find the 5mg vial size awkward for serial dilution because you basically get a small amount of powder that sticks to the glass, so a 10mg or 20mg vial is actually easier to handle.

So for ordering, we ship any quantty form 10, and payment terms are net 30 for accounts with history—otherwise it's prepay, and we typically have stock but confirm lead time if you need over 50 boxes.
We typically require a minimum of 10 vials per order, but you can mix sizes within the same box. So if you need 5mg vials, that's one box of 10; if you want 20mg vials, same deal.
Yes, we include a CoA with every batch that confirms the 99% purity by HPLC. Just let us know when you place the order, and we'll send it along.
We usually ship within 2-3 business days after payment confirmation. International delivery can take 7-14 days depending on customs, but we'll provide tracking once it's out.
We only offer those three vial sizes, and they come prepacked in boxes of 10. Custom vial sizes aren't available, but you can order multiple boxes of different sizes if needed.
Keep it in a cool, dry place away from direct sunlight—room temperature is fine, but a fridge is better if you want maximum stability. Once reconstituted, use it quickly and store at 2-8°C.
