TB-500 is a synthetic peptide modeled after the naturally occurring Thymosin Beta-4 (TB4), a protein present in most human and animal cells. TB4 plays a crucial role in tissue regeneration, particularly by enhancing cell migration and stimulating the formation of new blood vessels. It is secreted by platelets and macrophages in response to injury, helping to mitigate inflammation, prevent cellular damage, and lower the risk of infection. TB-500 replicates the functional activity of TB4 and is widely studied for its potential benefits in wound repair and tissue recovery.
TB4/ TB-500
This research peptide is defined by the molecular formula C₂₁₂H₃₅₀N₅₆O₇₈S, with a molecular weight of 4963.5 g/mol. The amino acid sequence is:
Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser.Purity is confirmed through analytical testing and detailed in the accompanying Certificate of Analysis. This sequence corresponds to the full-length synthetic analog of Thymosin Beta-4, commonly known as TB-500, studied for its regenerative and anti-inflammatory properties in preclinical models.
