We've got a lab running chronic wound healing models that needed something better than the generic growth factors they'd been using — the 99% purity on this should keep batch-to-batch variability low, and the -20°C storage requrement isn't ideal for everyone, but we usually have stock, so confirm lead time (roughly 10-14 business days for the standdard 10-vial case).
CAS is 885340-08-9, molecular weight comes in at 834.96 g/mol, and it's a in 10mg per vial — most buyers go with the 10-vial box to start, since the MOQ on singles isn't worth the shipping cost anyway. Purity is ≥99% by HPLC, which is tighter than reagent grade for this peptide class, and the COA form the batch we tested showed no detectable endotoxins.
It basically promotes cell migration and actin upregulation in tissue repair models, which is why it keeps popping up in muscle and cardiac regeneration studies — but it's not suited for acute inflammation models, since the anti-inflammatory effect is pretty mild and takes 20 days or so to show measurable differences. One thing I noticed handling the powder: it's hygroscopic, so you'll want to reconstitute it imediately after opening or store it in a desiccator, which isn't on the spec sheet but matters in humid climates.
Also, the formula is C38H62N10O12, and the sequence is acetylated at the N-terminus — that's the modification that gives it better stability than the endogenous version, though we don't have full TDS on the exact salt form. You'll need to order the box of 10 vials to get teh best per-vial price, about $47 each instead of $65 for singles.
A single box contains 10 vials, each with 10mg of TB-500. We typically sell by the box, so that's your starting MOQ, but if you need a smaller sample for testing, just let us know and we can arrange that.
We usually ship within 3–5 business days after payment is confirmed. If you need it faster, we can prioritize rush orders for an extra fee.
Yes, every batch comes with a COA that shows the ≥99% purity and confirms identity via HPLC. Just request it when you place your order, and we'll include it.
Keep it at -20°C in a freezer, away from light and moisture. The vials are sealed tight, so as long as you don't open them until use, they'll stay stable for months.
Our standard is 10mg per vial, 10 vials per box, but we can adjust the vial count per box or the mg per vial for bulk orders. Just tell us your specs, and we'll see what works.
