For a single vial it's $45, mid-range orders of 5-10 vials drop to about $38 each, and bulk buys of 20 or more vials run roughly $32 per vial — we usually have stock but confirm lead time for larger quantities.
Basically what you're getting is a lyophilized powder at 99% purity, which is better than reagent grade for most actin-binding studies. The molecular weight sits at 4963 g/mol with that long Ac-Ser-Asp-Lys sequence you'd expect for TB-500. It ships in 10mg vials, ten to a box, and you'll want to store it refrigerated — don't freeze it though, that can mess with cake structure. Most buyers go with the 10mg format because of that it's easier to reconstitute for dose-response work, though some labs prefer smaller aliquots for less waste.
Also, it's not suited for anything involving live animal models without further purification work — the peptide's fine for cell culture and in vitro assays, but we've seen issues with residual TFA if you're pushing sensitive systems. One thing you wouldn't think to ask: the lyophilized cake can look slightly off-white sometimes, that's normal for this CAS number (885340-08-9) and doesn't affect purity.
20 days or so is typical for delivrey on stock orders, though custom batches might run closer to 30. We've handled enough of this peptide to know teh vial stoppers hold up well under reconstitution — just don't vortex too aggressively or you'll get foaming.
Anyway, the cost-effectiveness comes form the bulk pricing structure — if you're running multiple assays, the per-vial savings add up quick. The 99% purity is consistent batch to batch (we run HPLC on every lot), but we don't guarantee it for anything beyond research use.
Our standard MOQ is 10 vials, which matches the 10mg*10vials packaging. If you need a smaller quantity for initial testing, let us know and we can sometimes accommodate.
We usually ship within 1-2 business days after order confirmation and payment. For larger custom orders, it may take up to 5 days.
Yes, we include a COA with every batch, showing HPLC results confirming the 99% purity. Third-party testing reports are available upon request.
Store the lyophilized powder refrigerated at 2-8°C, and do not freeze. After reconstitution, keep it refrigerated and use within 30 days for best stability.
We can customize the vial count or mg per vial for larger orders. Just share your requirements, and we'll work out the pricing and lead time.
