TB-500 is a synthetic peptide derived from thymosin beta-4 (Tβ4), a naturally occurring 43-amino-acid protein that is widely studied in cell-biology research. Research-grade TB-500 is commonly built around the actin-binding region of Tβ4, making it a popular research peptide for in-vitro studies of actin dynamics.

KYVEC supplies TB-500 as a lyophilised (freeze-dried) powder in a sealed, labelled vial, packed in our signature KYVEC black box. Each label shows the product name and quantity, so stock can be logged and tracked in your lab inventory as soon as it arrives.

Storage and handling: Store unopened vials in a cool, dry place away from light. For long-term storage, refrigerate (2–8°C) or freeze (−20°C). Once reconstituted for laboratory use, keep refrigerated and avoid repeated freeze–thaw cycles. Handle with standard laboratory PPE.
