TB-500 (Thymosin B4 Acetate)

Description

TB-500 (Thymosin Beta-4 Acetate) is a synthetic version of Thymosin Beta-4, a naturally occurring 43-amino acid peptide found in virtually all human and animal cells. As the primary actin-sequestering molecule in eukaryotic cells, Thymosin Beta-4 plays a fundamental role in cytoskeletal organization, cell migration, and tissue repair. TB-500 has been extensively studied for its roles in wound healing, angiogenesis, anti-inflammatory responses, and cell differentiation. The peptide promotes tissue repair by upregulating cell-building proteins such as actin, facilitating the migration of endothelial cells, keratinocytes, and other repair cells to sites of injury. TB-500 also influences the expression of laminin-5 and other extracellular matrix proteins involved in basement membrane assembly. Research has demonstrated its ability to modulate inflammatory cytokines and promote anti-inflammatory pathways. Supplied as a lyophilized powder. For research use only.
