If you're stocking up for a lab in the US that does a lot of wound healing studies, we ship these vials with the standdard COA and a simple TDS that usually clears customs fine—though for EU or UK orders you'll want to confirm we include the MSDS and origin docs (usually 2-4 weeks lead time for that paperwork).
Comes as a in 2mg, 5mg, or 10mg vials, with purity checked by HPLC at 99% or better—the 10mg vials are more common for larger assays but the 2mg is easier if you're testing small doses or dosing multiple animals without waste.
What it does is mimic the active fragment of thymosin beta-4, so researchers use it for endothelial cell differentiation assays or collagen deposition work, but it's not a full-length protein—so don't expect it to replicate everything teh natural peptide does in vivo, that's a pretty common misunderstanding.
Also, storage is at -20°C in dry conditions, and we've found that if you keep the desiccant pack in box, the powder holds up for the full 24-month shelf life—but if you open a vial and leave it out, it'll clump within a week or so.
Anyway, we usually have stock in the 5mg and 10mg sizes for US and EU buyers, but the 2mg can run short—check lead time before ordering if you need that specific fill.
We require a minimum order of 1 box, which contains 10 vials. You can mix different strengths (2mg, 5mg, 10mg) within that box if needed.
Orders are usually shipped within 3-5 business days after payment confirmation. For larger bulk orders, it may take up to 10 days.
Yes, we include a COA with every batch showing ≥99% purity verified by HPLC. Just let us know the batch number and we'll send it over.
We can do private labeling and custom packaging for orders of 100 boxes or more. Vial sizes are fixed at 2mg, 5mg, or 10mg, but we can pack them in bulk bags if needed.
Keep them at -20°C in a dry, airtight container. Avoid freeze-thaw cycles—once reconstituted, use immediately and do not refreeze. Proper storage ensures the full 24-month shelf life.
