TB-500 Manufacturer 10vials/Box White Powder CAS 885340-08-9 Supply

it come from the thymus gland or, more accurately, it's a synthetic fragment of a natural peptide called thymosin beta-4. What it does is it binds to actin, a key structural protein in cells, helping to regulate cell migration, so researchers in tissue repair and angiogenesis studies often use it. We've found buyers working on models of wound healing or muscle recovery will usually pick this up.

if you're looking at something like acute cardiac injury or severe dermal wound models, this is an area where the R&D really gets interesting. But it's not for anything involving direct human or veterinary applicaion—this is strictly research-use-only material. Most labs our company supply go with the 10mg vials over 5mg, just because the dosage flexibility is better. Expect roughly 24 months of shelf life if you store it cool and dry.

We run HPLC on every single batch, so you're getting 99.0% minimum purity verified by third-party analysis—we've got COAs on file for each lot. There's no guesswork on teh spec sheet; we basically test for both identity and purity, and the consistency has been solid over the past few years. You can ask for the batch-specific HPLC trace.

The packging is a white powder in sterile vials, and each box holds 10 vials. We usually have stock, but confirm lead time—sometimes it's 2-3 weeks, sometimes a bit longer if demand spikes. One thing we get asked all time: the CAS number is 885340-08-9, but the molecular weight—889.02 g/mol—matters more when you're reconstituting for assays. Storage is straightforward.
