We’ve seen a lot of interest in this peptide mainly because of how it fits into wound healing and inflammation studies — it’s not every day you get something with this kind of cellular signaling profile. Basically, what it does is bind to actin and promote cell migration, which is why researchers keep coming back to it for tissue repair models. Most buyers go with the 10mg vials, and that’s typically enough for a solid set of experiments without tying up too much budget.
The CAS is 885340-08-9, and the molecular weight comes in at roughly 889 g/mol, which matters for accurate reconstitution when you’re calculating molarity. It’s a, and we check every batch by HPLC — purity runs 99.9% minimum, give or take a decimal. Solubility is a bit tricky: slightly soluble in water and methanol, so you’ll want to use something like sterile water or bacteriostatic water for reconstitution, then maybe buffer it.
Store it in a cool, dry place and you’ve got 24 months shelf life, but we usually have stock ready to ship within 20 days or so. It’s pharmaceutical grade, which means the tolerance on residual solvents and endotoxins is tighter than what you’d see in some research-grade peptides. Not suited for anything other than in vitro or in vivo research — this isn’t for human use, and pKa around 3.2 tells you it’s stable at physiological pH ranges.
Packaged as 10mg per vial, ten vials to a box — that format works well for labs that run or need multiple aliquots without cross-contamination. Teh density is predicted at about 1.28 g/cm³, but honestly most people don’t check that unless they’re doing something very specific with solubility mechanics. One thing buyers don’t always think to ask: the lyophilized cake can be brittle, so handle the vials carefully when reconstituting.
We’ve had a few customers ask about the boiling point, which is predicted around 1405°C, but that’s not a practical concern for standerd research protocols — it’s more of a reference number. The molecular formula is C38H68N10O14, and there’s a fragment structure that mimics the actin-binding domain of thymosin beta-4, which is what drives the mechanism in cell motility assays. Anyway, if you’re working with cell culture, this tends to be more consistent than some other sources we’ve tested.
Our MOQ is 1 box, which contains 10 vials, each with 10mg of TB-500. So you can start with just one box.
We usually ship within 3-5 business days after payment confirmation. If we have stock, it could be even faster.
Yes, absolutely. Each batch comes with a COA showing the 99.9% minimum purity by HPLC, plus other specs like appearance and molecular weight. Just ask for it.
It's only slightly soluble in water and methanol, so you'll need to check the specific solvent for your research. Store it in a cool, dry place, and it'll stay good for 24 months.
Yes, we can customize the packaging to your needs, whether you want different vial sizes or more vials per box. Just tell us what you need, and we'll work it out.
