When you're working with actin-binding studies and teh standdard peptides just don't hold up under extended assays, that's where this one steps in—it's built for consistency where others degrade too fast.
What it does is mimic Thymosin Beta-4's natural role in modulating actin polymerization, so you get reliabel cell migration and proliferation data without the batch-to-batch drift that messes up longitudinal work.
We run it at ≥99% purity by HPLC, molecular weight checks in at 4963 g/mol, and it's lyophilized as a white powder in 10mg vials (10 per kit, so 100mg total give or take). CAS is 885340-08-9.
Storage is pretty straightforward at 2-8°C, protected from light and moisture, and we usually have stock on hand but confirm lead time if you need more than 50 kits or so.
Our MOQ for custom TB-500 is 10mg*10 vials, as listed in the standard packaging. We can discuss larger orders if you need more volume.
Lead time is usually 2-3 weeks after order confirmation, depending on current production schedule. Custom sequences may take a bit longer, but we’ll give you a firm timeline upfront.
Yes, every batch comes with a CoA showing purity by HPLC, mass spec verification, and other QC data. We can also share additional documentation like MSDS upon request.
Absolutely, we offer full customization of the sequence, vial size, and packaging format. Just let us know your specs, and we’ll tailor the production to fit your needs.
Store at 2-8°C in a dry place, away from light and moisture. Under these conditions, the peptide stays stable for up to 24 months.
