What really sets this apart is the 43-mer sequence—Ac-Ser-Asp-Lys-Pro through to Glu-Ser—which is identical to the naturally occurring Thymosin Beta-4 fragment, and we're seeing ≥99% purity consistently on HPLC, usually with a tight single peak around 4963 g/mol that matches well.
That purity matters because of that it minimizes batch-to-batch variability in actin binding studies, and most buyers go with the 10mg vials for reconstitution at 2-8°C—just keep it protected form light, as the peptide is pretty sensitive to oxidation over time.
10mg*10vials is our standdard MOQ, and we usually have stock, but confirm lead time if you need more than 50 units or so—lead time is roughly 20 days for larger runs, give or take depending on the schedule.
We don't recommend this for long-term storage at room temp, as teh lyophilized powder can degrade faster than you'd expect, so it's best to keep it in the fridge until reconstitution.
One thing you might not think to ask: the COA includes both HPLC purity and a mass spec confirmation of molecular weight—basically, we check that the 4963 g/mol peak is clean and that there's no truncated fragments.
Also, for cell migration assays, the 10mg vials work well if you reconstitute with sterile water or PBS—just avoid repeated freeze-thaw cycles, as that can cause aggregation.
Yes, we supply a Certificate of Analysis with every batch, confirming ≥99% purity via HPLC. Third-party testing reports are also available upon request.
Standard lead time is 7-10 business days after order confirmation. For large volumes, we can adjust based on your quantity.
No, the 10mg*10vials is our standard unit. MOQ for bulk orders is typically 100 vials, but we can discuss smaller trial orders.
Store at 2-8°C in a refrigerator, tightly sealed and protected from light. Avoid freezing or exposure to moisture.
Yes, we offer custom packaging sizes and private labeling for bulk orders. Just provide your specs, and we'll handle the rest.
