Where to Buy TB-500 Peptide – Research Overview

TB-500 is a synthetic peptide fragment derived from the naturally occurring protein thymosin beta-4 (Tβ4). It corresponds to the actin-binding domain of the full thymosin beta-4 protein.

Thymosin beta-4 is a 43-amino acid protein found in virtually all human and animal cells. It plays a fundamental role in cytoskeletal organization through its high-affinity binding to G-actin monomers.

The TB-500 fragment retains many of the biological activities associated with full-length thymosin beta-4, making it a widely used tool compound in tissue biology and repair research.

Research Applications

Actin Regulation Research

TB-500 binds to G-actin monomers with high affinity, sequestering actin and influencing cytoskeletal dynamics.

Researchers have used TB-500 to study actin polymerization, cell migration, and cytoskeletal reorganization in various cell type models in vitro.

Tissue Repair and Regeneration

TB-500 has been studied extensively for its role in promoting cell migration and proliferation relevant to tissue repair processes.

Research programs have examined its effects on fibroblast, keratinocyte, and endothelial cell activity in wound healing models.

Angiogenesis Research

TB-500 has been studied for its effects on endothelial cell migration and blood vessel formation — key components of the angiogenic response to tissue injury.

Cardiac Research

Thymosin beta-4 and its fragments have been investigated in cardiac biology research, including studies on cardiomyocyte survival, cardiac progenitor cell activation, and myocardial repair mechanisms in preclinical models.

Frequently Asked Questions

Why do researchers buy TB-500 peptide for lab studies?

Researchers buy TB-500 peptide to study actin dynamics, cell migration, tissue repair mechanisms, angiogenesis, and cardiac biology. Its role as a thymosin beta-4 fragment makes it relevant to multiple cell biology research programs.

What is the difference between TB-500 and thymosin beta-4?

Thymosin beta-4 is the full 43-amino acid protein. TB-500 is a synthetic fragment corresponding to its actin-binding domain. TB-500 retains the core biological activities while being more accessible for research synthesis and supply.

What purity level does your TB-500 meet?

All AMP TB-500 is independently verified at ≥98% purity by third-party HPLC analysis. A full COA is available for download.

How should lyophilized TB-500 be stored?

Store at -20°C in a dry, light-protected environment. Once reconstituted, store at 4°C and use within 30 days. Do not refreeze.
