Description

Product Detail

Thymosin Beta-4 (Tβ4), also commonly known as TB-500, is a high-purity synthetic peptide compound that replicates the structure and functional characteristics of natural active peptides, composed of 43 amino acid sequences. As a biologically active substance widely present in human and animal organisms, this natural-derived peptide boasts excellent biological compatibility and safety, making it a premium raw material for functional health and body care products.

This core peptide ingredient exerts multiple beneficial biological effects in physiological regulation and tissue maintenance. It effectively supports the repair and renewal of damaged cells and tissues by moderating unnecessary cell apoptosis, relieving abnormal inflammatory responses, and inhibiting the proliferation of harmful microorganisms in damaged areas. It can be naturally secreted and released by a variety of somatic cells in the body, such as platelets and macrophages, ensuring stable and effective biological activity.

After acting on the body, Tβ4 can specifically bind to actin in cells, effectively facilitating the migration of somatic cells and promoting the differentiation and development of stem and progenitor cells. This mechanism helps accelerate the formation of new blood capillaries, improves local blood circulation and nutrient supply, and further boosts tissue repair and regeneration efficiency. Numerous professional studies have verified its reliable effect on accelerating wound recovery and optimizing skin and tissue physiological status, with stable performance and mild action, suitable for various high-end functional product formulations.

Research

Class:

Actin-sequestering protein / 43-amino-acid peptide

Status:

Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)

Mechanism:

A naturally occurring 43-amino-acid peptide (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-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.

Activity note:

Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
