It’s a synthetic fragment of Thymosin β-4, CAS 885340-08-9, with a molecular weight of 889.01 g/mol and ≥99% purity by HPLC, we supply it as a white to off-—pharmaceutical grade, not reagent grade—so you’re working with tighter tolerances than most generic peptides.
biological activity centers on actin polymerization and extracellular matrix synthesis, which is why it shows up in tissue regeneration and angiogenesis research. It also modulates cytokine-driven inflammation, but it’s not suited for direct in vivo work without proper formulation—basically, don’t expect it to dissolve instantly in saline without some gentle agitation. We’ve seen it perform better than standard fragments for dermal repair studies, though cardiovascular appliction usually require a longer protocol window (20 days or so). One thing most buyers don’t ask about: the lyophilized cake can be brittle, so reconstitute slowly to avoid foaming.
Storage is at 2-8°C, and it must stay protected form light—we usually have stock, but confirm lead time if you need more than 50 vials. Teh 5mg per vial format is common, and we can do 10 vials per kit or custom packaging if you’re running a large batch.
And the ordering part is straightforward: MOQ is typically one kit, but we can adjust for bulk. You’ll get a COA with each lot, and the HPLC trace is included—no need to chase down specs after delivrey.: we don’t recommend using it for cell culture without sterile filtering first, even though it’s pharmaceutical grade.
So it’s relaible peptide for research, but it’s not a plug-and-play solution for every protocol. Most buyers go with the 10mg kit for flexibility, but the 5mg vial is easier to handle if you’re testing multiple conditions.
We're flexible on MOQ. For stock 5mg/vial kits, you can order just 1 kit. For custom packaging or larger bulk, we typically ask for 50 kits or more, but we can discuss your exact needs.
Standard lead time for bulk TB-500 is 7–15 business days after order confirmation, depending on the quantity. Custom labels or packaging might add a few extra days.
Yes, we include a COA with every batch showing ≥99% purity by HPLC. You'll get the actual test report for that specific lot number.
Absolutely. While standard is 5mg/vial and 10 vials per kit, we can do custom vial sizes, bulk powder in bags, or private labeling. Just share your specs and we'll quote.
Store it at 2-8°C in a fridge, protected from light. It's a lyophilized powder, so keep it sealed and dry. Once reconstituted in sterile water or buffer, use it within a few days.
