TB-500 (Thymosin Beta-4) Delayed Release Capsules

TB-500 is a synthetic peptide known to support tissue repair and flexibility. Discover how it enhances cell migration and recovery mechanisms.

This product is prepared for LABORATORY RESEARCH 
USE ONLY and may not be used for other purposes.

Chemical Structure and Properties

TB-500 corresponds to the active domain of Thymosin Beta-4, specifically containing the central actin-binding sequence (Leu-Lys-Lys-Thr-Glu-Thr-Gln); its molecular formula varies slightly based on the specific fragment length used, but the full 43-amino acid sequence has a molecular weight of approximately 4963.5 g/mol. The peptide features an acetylated N-terminus, a modification that significantly enhances its stability and lipophilicity, allowing it to diffuse easily through tissues and travel systemically. Our preparations achieve purity levels exceeding 98% by HPLC, with consistent batch-to-batch reproducibility that we document transparently, ensuring you have reliable materials at hand.

Introduction to TB-500 Capsules

TB-500 is a synthetic analog of the naturally occurring protein Thymosin Beta-4, a key regulator of actin polymerization found in high concentrations in platelets and wound fluid. It is designed to support the body’s natural repair mechanisms by enhancing cell motility and modulating inflammation. By interacting with the cellular cytoskeleton, TB-500 facilitates the migration of reparative cells—such as keratinocytes and endothelial cells—to sites of injury. Our formulation provides a precise delivery method for this peptide, positioning it as a premier option for supporting musculoskeletal recovery, flexibility, and tissue maintenance.

In mechanistic terms, TB-500 functions primarily through its ability to sequester G-actin (globular actin). By regulating the availability of actin monomers, it controls the formation of actin filaments, which are the structural "tracks" cells use to move. This cytoskeletal reorganization is critical for rapid tissue repair. Mechanistically, TB-500 also influences angiogenesis by promoting the differentiation of endothelial cells and helps prevent the deposition of excessive fibrous tissue (scarring)—we're happy to walk through the data behind these pathways, offering straightforward interpretations grounded in the science.

About the Capsules

  • Function: GAR (Gastric Acid Resistant) capsules are designed to be acid-resistant, meaning they do not dissolve in the highly acidic environment of the stomach.
  • Purpose: They are used to deliver sensitive ingredients—safely through the stomach and release them in the intestines.
  • Targeted Release: These capsules are pH-sensitive; they remain intact in the stomach and only release their contents when the pH changes from acidic to neutral in the upper intestine.
  • Material: They are made from HPMC (Hydroxypropyl Methylcellulose), a plant-derived (vegan/vegetarian) material, making them a popular alternative to traditional gelatin for enteric (delayed-release) delivery.

Mechanisms and Applications

TB-500’s role as a driver of cell migration makes it a subject of significant interest for athletic and systemic recovery. In musculoskeletal models, it is noted for reducing inflammation and promoting the healing of tendons and ligaments, which are typically slow to recover due to poor blood flow. Beyond structural repair, it supports cardiac health by promoting angiogenesis (new blood vessel formation) and reducing oxidative stress in heart tissue. Its ability to minimize scar tissue formation while maximizing functional recovery makes it a versatile tool for maintaining long-term physical resilience. We appreciate the nuance in these biological actions and are here to provide insights into how this peptide supports cellular mobility, keeping things logical and approachable.

For optimal stability, store TB-500 capsules in a cool, dry environment, preferably at 4°C to -20°C, keeping the container tightly sealed to shield from humidity and light. If extracting contents for solution-based needs, the peptide is highly water-soluble; reconstitute in sterile bacteriostatic water or physiological saline with gentle mixing. Backed by our stability validations, these steps help maintain integrity—reach out if you have questions regarding handling or storage.
