Lead time is usually about 2-3 weeks, but we've seen it stretch to 4 or so when demand spikes — the cold chain shipping is standard, with dry ice and insulated packaing, and we do track it form dispatch to dilevery.
It's really only for research use, not for human or animal consumption, so if you're working with live subjects or clinical trials that's a non-starter, but for in vitro studies or receptor binding work the qualiy is actually solid.
Purity runs at 99.9% or better by HPLC, which is tighter than most generic sites, and white powder reconstitutes cleanly in sterile water or buffer — we've had customers run comparative assays against reference standdard and it holds up.
10 is the minimum order, each vial contains 10mg of the lyophilized powder, and you'll want to store it at 2-8°C away from light — basically, if you leave it on the bench overnight it's junk by morning.
The 10mg per vial is pretty convenient for most protocols since you can resuspend at 1 mg/mL in bacteriostatic water, but some buyers actually prefer the 5mg vials for smaller batch work — we don't carry those, but it's a common ask.
From what we've seen, the PEG modification on the lys side chain improves water solubility without messing with activity, though exactly how much better it is in practice we don't have hard numbers for.
We require a minimum of 10 vials per order. That's one box, so you're getting 100mg total.
We test every batch with HPLC before shipping. The certificate of analysis confirms the ≥99.9% purity, and we can share that with you on request.
Keep it at 2-8°C in a fridge, and make sure it's protected from light. Room temp or sunlight will degrade the material, so a cool dark place is key.
Each order comes with a Certificate of Analysis showing the HPLC purity results and batch details. We can also supply an MSDS for safety handling.
Right now, it's only offered as 10mg per vial, with 10 vials per box. We don't have other sizes or custom packaging options available at this time.
