TB-500 is commonly used as a research label for Thymosin Beta-4 (TB4), a naturally occurring peptide widely expressed in mammalian tissues. In research settings, Thymosin Beta-4 has been studied for its interactions with actin (cytoskeletal organization), and for its role in signaling cascades involved in cell migration, tissue remodeling, and angiogenesis-related responses.

This product is supplied as a lyophilized powder intended strictly for laboratory research applications.
