Getting consistent actin polymerization in your cell migration assays can be a real headache when the peptide degrades before you even get it in solution — we’ve seen labs lose a week’s work to batch variability.
What you’re after is a 43-amino-acid sequence that mimics Thymosin Beta-4’s binding domain, and this one’s got the exact Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH chain with 99.9% purity by HPLC, which basically means you’re not chasing impurities instead of mechanism.
It’s a in alumnum foil bags, and most buyers go with the 10mg vial for (check lead time on 5mg if you’re doing pilot runs). Store it cool and dry, or you’ll lose activity within weeks.
Not suited for anything beyond research use — don’t expect it to hold up in serum-rich environments without proper reconstitution buffer, and teh 885340-08-9 CAS is specific to this sequence, so double-check your reference standerd.
We usually have stock, but confirm lead time if you need 50 units or more; the 5L drum is easier to handle for bulk work, but the 10mg vials give tighter tolerance for exact dosing.
Our TB-500 peptide powder is tested at 99.9% purity, pharmaceutical grade. That's verified by HPLC and mass spec analysis.
We offer 5mg and 10mg vials, both packed in aluminum foil bags for protection. MOQ is flexible, starting from single vials.
We include a Certificate of Analysis (CoA) with each batch, showing purity, sequence confirmation, and residual solvents. Third-party lab reports are available on request.
Keep it in a cool, dry place away from light and moisture. The aluminum foil bag helps, but long-term refrigeration at 2-8°C is recommended for stability.
We can adjust vial sizes or packaging labels for bulk orders, but standard 5mg and 10mg vials are ready to ship. Just let us know your needs.
