We've seen a steady uptick in labs requesting custom TB-500 for cytoskeletal studies, and it's pretty much go-to for anyone looking at actin dynamics in wound healing models.
The we ship is 99% pure by HPLC (we run a COA with every order), and the molecular weight comes in at 4963 g/mol — that's the full-length sequence, not a fragment — so it's better than some truncated versions floating around.
You'll get 10mg per vial, which is usually enough for 20-30 doses depending on your protocol, and it's stored at 2-8°C in teh dark (check lead time if you need it outside those conditions, as we usually have stock but not always).
Actually, one detail buyers don't always ask: this TB-500 isn't great for long-term stability at room temp, so don't leave it on the bench overnight — it'll degrade faster than most peptides.
Basically, what it does is mimic Thymosin Beta-4's role in actin sequestration, which is why those cell migration assays work so well with it, though for chronic inflammation studies you might prefer the 5mg or 10mg depending on your batch.
Anyway, for research grade materail the purity tolerance is tighter than reagent grade — roughly 98.5% to 99.5% is typical, but we lock in at 99% give or take 0.2%.
We can do single vials for small-scale studies, but our standard MOQ is 10 vials per lot to keep the process efficient. If you need fewer, just let us know and we'll see what we can arrange.
Lead time is usually 2-3 weeks from order confirmation, depending on current workload. For rush orders, we can sometimes expedite to 10 business days.
Yes, every batch comes with a CoA that includes HPLC purity results, mass spec verification, and molecular weight confirmation. We can also share the raw data if needed.
Keep it at 2-8°C in the original vial, tightly sealed and away from light. Under those conditions, it stays stable for at least 12 months. Avoid freeze-thaw cycles after reconstitution.
Absolutely, we can adjust vial sizes to your needs, whether it's 5mg, 20mg, or another amount. Just specify the requirement when placing the order, and we'll handle the rest.
