You're chasing a consistent synthetic peptide for actin-binding studies or cell migration assays, and real headache isn't finding a suplier—it's getting materail that doesn't degrade before you can run your dose-response. Most generic TB-500 hits come with purity claims that barely clear 95%, and that 5% impurity load can trash your baseline data. We've seen labs waste weeks re-running experiments because the peptide they got had truncated sequences or residual TFA messing with solubility.
What our company supply is lyophilized form a pharmaceutical-grade process targeting 99.9% purity by HPLC, and we put a COA in every sealed vial shipment so you can verify that before it goes into buffer. The sequence is Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH at CAS 885340-08-9, so there's no ambiguity about what you're reconstituting—it's the full 43-amino-acid analog, not a fragment. We usually stock batches in 5mg and 10mg vials, but the MOQ is flexible if you need bulk for a large study.
Molecular weight sits at 854.99 g/mol, and the stores stable for 18 months or so in a cool, dark cabinet—just keep it desiccated. We don't recommend this for in vivo work unless you've got your own formulation and ethics approval, because the excipient is minimal and designed for reconstitution in PBS or water for injection. Honestly, most buyers go with the 10mg vial because of that it gives you enough for a couple of dilution series without opening a new bag every week.
Lead time is typically 7-10 business days from order to dispatch, and we ship in aluminum foil pouches with sealed vials inside to block light and moisture. One thing we've noticed is that labs sometimes forget to store teh reconstituted peptide below -20°C after first use—it degrades fast at room temp, and that's where the purity drop happens. We include a storage note on the packing slip, but it's worth flagging anyway.
Our MOQ for TB-500 is typically 1 gram, but we can accommodate smaller orders for research purposes—just let us know your specific needs.
Yes, we include a COA with every batch, confirming the 99.9% purity and pharmaceutical grade. Just request it when placing your order.
It's packaged in sealed vials inside an aluminum foil bag to protect it from light and moisture, ensuring stability during transit.
Store it in a cool, dry place away from light—ideally at 2-8°C for long-term storage. Avoid repeated freeze-thaw cycles after reconstitution.
Absolutely, we can adjust vial sizes or add custom labeling for research orders. Just share your requirements, and we'll work out the details.
