Quick Answer \u2014 What is TB-500?<\/h3>\n

TB-500<\/strong> is a synthetic analog of Thymosine B\u00e8ta-4<\/strong>, a naturally occurring 43-amino-acid peptide with systemic healing activity. In published preclinical research it binds G-actin, stimulates angiogenesis via the VEGF\/KDR pathway, and modulates TGF-beta inflammatory signaling. Supplied in 2\u00a0mg to 10\u00a0mg lyophilized vials for laboratory research use only.<\/p>\n<\/div>\n

What Is TB-500?<\/h2>\n

TB-500<\/strong> is the laboratory designation for a synthetic analog of Thymosin Beta-4 (TB4)<\/strong>, a naturally-occurring 43-amino-acid peptide hormone found in nearly every cell of the human body. TB4 is most abundant in platelets, and is released at sites of tissue damage where it orchestrates cell migration, angiogenesis, and anti-inflammatory signaling. The synthetic research form \u2014 TB-500 \u2014 reproduces the biological activity of TB4 and is the most widely studied research compound in this class.<\/p>\n

The TB4 sequence is Ac-SDKPDMAEIEKFDKSKLKKTETQEKNPLPSKETIEQEKQAGES<\/em>, molecular weight approximately 4,963\u00a0Da. It is supplied as a high-purity lyophilized powder for reconstitution with bacteriostatic water. TB-500 is uitsluitend voor laboratoriumonderzoek<\/strong> and is not intended for human or veterinary diagnosis or therapy.

Mechanism of Action \u2014 Systemic Healing via Three Pathways<\/h2>\n

TB-500 is distinguished from most peptides by its systemic distribution and long circulating half-life<\/strong>, which allow a single administration to influence repair processes across multiple tissues simultaneously. The three primary mechanistic pathways in published research:<\/p>\n
