So you're looking at TB-500 — that's Thymosin Beta-4 fragment, CAS 885340-08-9, and it comes as a white powder. We typically stock it in 5mg or 10mg per vial, packed 10 vials to a box, and purity runs ≥99.0% by HPLC. It's pharmaceutical grade, not research grade, so the tolerance is tighter than most suppilers offer for this peptide.
Basically, it's a synthetic fragment of the natural thymosin beta-4 protein, and people in the field use it for studying cell migration and tissue repair mechanisms. 3-5 words. We've seen it work well for endothelial cell differentiation assays and dermal tissue models, but it's not suited for systemic wound healing studies unless you're careful with dosing — the half-life is short. Store it cool and dry, and you'll get 24 months out of it (usually).
One thing buyers don't always ask about is how it handles in solution — it's pretty soluble in sterile water or PBS, but don't expect it to stay stable for weeks once reconstituted. We recommend using it within a few days or so after mixing. Teh molecular weight sits at 889.02 g/mol, which matters if you're calculating molar concentrations for your protocol.
Most researchers go with the 10mg vials for repeated dosing studies, but if you're just screening, the 5mg format saves waste. Our MOQ is typically 10 vials, and we provide a COA with every batch — no need to chase that down seperately. Lead time is about 20 days give or take, though we usually have stock for common sizes.
Anyway, if you're responding to an RFQ, just know that the C38H68N10O14 formula means it's a peptide, not a small molecule, so handling requires some care — no vortexing aggressively, that'll degrade it. We don't have data for every buffer system, but HPLC purity is consistent batch to batch.
Our MOQ is 10 vials per box, but we can discuss larger bulk orders if you need more — just let us know the quantity you're targeting.
Yes, we include a COA with every batch, showing ≥99.0% purity by HPLC, molecular weight confirmation, and appearance. Just ask for it when you place your order.
Keep it in a cool, dry place, ideally below room temperature and away from moisture. The vials are sealed, but once opened, use it promptly and store in a desiccator if possible.
We can adjust vial sizes for larger bulk orders, but standard stock is 5mg and 10mg per vial, packed 10 vials per box. Let us know your needs, and we'll see what works.
It's labeled for research use only, but it's produced to pharmaceutical-grade specs — ≥99% purity, white powder, and consistent HPLC results. We don't sell it for human or veterinary use.
