Product Detail

1. Product Introduction

TB-500 BT10 is a synthetic polypeptide composed of 43 amino acid residues. The corresponding peptide sequence can be found in multiple mammalian cell types such as platelets and macrophages.

Laboratory research focuses on its binding characteristics with actin and related intracellular biological behaviors within cell model systems. All research results are limited to in-vitro laboratory environments.

This product is supplied as lyophilized powder for laboratory research only. It shall not be used for human administration, clinical trials or any medical application.

2. Structural & Characteristic Features

CAS No.:885340-08-9

Molecular Formula: C₃₈H₆₈N₁₀O₁₄

Molecular Weight:889.01

TB-500 BT10 adopts standardized solid-phase synthesis and HPLC purification process. The finished lyophilized powder possesses stable molecular structure and favorable water solubility.

Vacuum freeze-drying technology effectively slows molecular degradation and maintains molecular stability during transportation and low-temperature storage.

3. Main Research Application Directions

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.
