Look, if you're comparing peptide supliers and wondering about teh price-to-qualiy ratio—we've seen a lot of them, too, but this is the one where we landed because specs actually hold up under HPLC. 99% purity on a research-grade LL37, white powder, dissolves cleanly in water at 5 mg/mL (so you're not fighting solubility issues mid-experiment). That pKa around 13 means it handles basic conditions better than reagent grade for most cell-based work.
Most buyers go with the 10mg vials rather than opening larger containers if they're running short-term assays—reduces freeze-thaw cycles significantly. It basically stays stable at -20°C in dry conditions, but don't let it sit out at room temp too long or you'll see degradation within a couple days, anyway. 10mg*10vials per kit, give or take, depending on bulk order.
We ship form China, and lead time is usually around 20 days or so if we've got stock (which we usually do, but confirm before ordering). Documentation includes a COA with each batch, so you're not guessing at purity post-arrival. Not suited for anything beyond in vitro research—no human or veterinary appliction, period—so spin plates, not pills.
(always check the SDS before handling, just to be safe). Everyone asks about trust first——but what most don't think to ask is how the lyophilization was handled: flash-frozen under nitrogen, then vacuum-sealed, which is why it reconstitutes without clumps in under a minute. 5mg/mL solubility is repeatable lot-to-lot.
We typically require a MOQ of 100 vials per batch, but we can discuss smaller quantities for first-time clients or trial orders. Just reach out to confirm.
Standard lead time is 15-20 working days after order confirmation. Custom orders might take a bit longer depending on the specs, but we'll keep you updated.
Yes, we supply a COA with every batch, including purity data (99% by HPLC), solubility checks, and storage conditions. Just request it when you order.
Store it at -20°C in a dry environment, away from moisture and light. We recommend using it within 12 months of receipt to keep it stable.
Absolutely, we can adjust the vial count per box or even offer bulk packaging. Just let us know your desired spec and we'll confirm the pricing.
