A lot of labs we talk to are tired of chasing down suppilers who can't get the paperwork right for customs, especially when you're shippng into US or the EU, and we've been handling that side of things for years now so it's pretty much routine for us.
It's the synthetic version of thymosin beta 4 with that specific sequence—Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH—and CAS 885340-08-9, but what matters for your work is the 1% content on a food grade white powder that stores in a cool dry place, roughly 20 days or so after production.
Most buyers actually go with this for cell culture work rather than anything in vivo, since it's not suited for clinical use at all, and we always include a COA with each batch so you're not guessing on purity.
The powder itself handles well at room temperature during transit, though we recommend keeping it sealed until you're ready to reconstitute, and if you need the packaging customized for smaller MOQs or specific vial sizes we can do that too, usually within 2-3 weeks lead time.
For import, we provide all the standard docs—TDS, SDS, and a certifcate of origin—which covers most EU and UK customs requirements, but confirm your local regulations since some countries have tighter rules on polypeptides.
Anyway, we ship form our facility in 50-gram or 100-gram drums, and the 5L drum is easier to handle for bulk orders, but stock levels vary so it's best to check availability before placing a large order.
We can supply as low as 1 gram for trial orders. For larger production runs, we offer volume discounts starting at 10 grams.
Yes, we include a COA with every batch showing purity, content, and appearance. Third-party testing reports are available on request.
Keep it in a cool, dry place away from light and moisture. For long-term storage, we recommend freezing at -20°C in a sealed container.
We can customize packaging sizes from 1g to bulk quantities. For sequence modifications, please contact us with your specific requirements.
Standard orders ship within 3-5 business days after payment. Rush orders can be processed in 24-48 hours, but may incur extra charges.
