We're looking at the 43-amino acid peptide, and basically it's a synthetic version of Thymosin Beta-4—your CAS number is 885340-08-9, with that molecular weight around 4963 g/mol, and purity hits ≥99% by HPLC, which matters because consistent results in tissue repair studies depend on it.
Actually, most buyers go with the 10mg * 10 vials format since it's easier to aliquot for them, and we usually have that in stock, but confirm lead time if you need a large quantity; storage is 2-8°C, dark and dry, and we don't recommend this for anything chronic or vascular unless you've validated your own protocol first.
So on reliability, we've handled enough batches to know lyophilized powder is what it is—white, consistent, and it reconstitutes cleanly—but one thing you don't often think to ask: we check every COA against the reference standard, though our in-house HPLC can vary give or take 0.2%.
For almost any research application that involves actin polymerization or tissue repair studies, it works fine, but it's not suited for wound healing —that's a separate product—and honestly, we ship it double-sealed in a thermal pouch with ice packs, typically 20 days or so door-to-door.
We generally don't negotiate MOQ below 100 vials or so, but if you need a trial sample first, just flag that, and our company can include the SDS and MSDS with the order—no hidden fees form clearing customs, (usually 2-4 weeks for standerd shippng).
Standard lead time is 3-5 business days after payment confirmation. Rush orders may be available upon request.
Yes, we include a COA for every batch showing ≥99% purity verified by HPLC. Just ask for it when you place your order.
The MOQ is 10 vials, which matches our standard 10mg*10vials packaging. Larger quantities are available with discounted pricing.
Store it at 2-8°C in a dry, dark place. Once reconstituted, use immediately or keep refrigerated and use within 24 hours for best results.
Yes, that's correct. The molecular weight of 4963 g/mol aligns with the full 43-amino-acid sequence of TB-500. Double-checked against our specs.
