Custom TB-500 Peptide Manufacturing - 4514.04 Molecular Weight Research Compound

We've been running this custom TB-500 for a while now, and it's basically teh synthetic version of Thymosin Beta-4—the 4514.04 molecular weight compound that researchers typically keep at -20°C for stability. Most buyers go with the 1g per vial packaging, but we can adjust that if your lab needs a different format.

It works by regulating actin processes in cells, which is pretty much why it shows up in studies on recovery and inflammatory response management. Not great for direct in vivo work without proper protocols, though—this is strictly research use only. The solubility gets tricky: you'll need ammonium hydroxide above pH 9 or DMSO to get it into solution.

Purity runs at 99% by HPLC, pharmaceutical grade, and we usually have stock ready for US, EU, and UK shipments. CAS is 107761-42-2, molecular formula C203H311N55O60S1—that sulfur atom makes a difference in how it folds, actually. We include a COA with every batch, and for import docs our company can supply the TDS and SDS without extra hassle.

What it does is help manage cellular signaling around actin binding, so researchers looking at muscle cell formation or metabolic functions often turn to this. The 4514.04 g/mol weight means it's a larger peptide—tighter tolerance than some generic suppilers offer. We've handled enough orders to know lead times are roughly 20 days or so form order, but confirm if you need it faster.

Anyway, one thing you might not think to ask: vial packging is under argon to reduce oxidation, which matters for long-term storage at -20°C. Also, we've seen labs use this for wound healing models and cardiac recovery studies. Not something you'd run in a standard buffer without testing solubility first—DMSO is usually the safer bet.
