Thymosin Beta 4, commonly referred to as TB500, is a synthetic version of a naturally occurring thymosin peptide found in many tissues throughout the body. It has been studied in preclinical research for its involvement in cellular migration, tissue repair, and cytoskeletal organization.

• Molecular Formula: C₃₈H₆₈N₁₀O₁₄
• Molar Mass: 889.0 g/mol
• CAS Number: 885340-08-9
• PubChem CID: 16132341

Rather than acting through a single pathway, Thymosin Beta 4 has been examined for its role in coordinated cellular responses during tissue remodeling and recovery processes. TB500 5 mg is supplied as a lyophilized powder in sterile vials and is intended strictly for laboratory research use only. Research facilities that buy thymosin peptide often use musculoskeletal, vascular, and wound-healing model systems.

TB500 is a well-characterized peptide fragment with extensive preclinical research supporting its relevance in tissue dynamics. It remains a non-clinical research compound.

• Peptide identity: Synthetic Thymosin Beta-4 fragment (TB500)
• Primary research focus: Cell migration, tissue remodeling, and repair mechanisms
• High-purity format: Pharmaceutical-grade lyophilized peptide powder
• Research applications: Muscle, tendon, ligament, skin, and vascular model systems
• Molecular consistency: Manufactured for sequence accuracy and stability
• Regulatory status: For laboratory research use only. It is available to qualified researchers who order thymosin peptide from authorized suppliers

The thymosin peptide TB500 has been studied for its interaction with actin, a structural protein involved in cell shape, motility, and intracellular transport. In preclinical models, TB500 has been associated with cell migration, angiogenesis-related pathways, and extracellular matrix remodeling.

Research investigations have explored TB500 in:

• Soft-tissue and musculoskeletal injury models
• Angiogenesis and vascular development studies
• Inflammation-modulated repair processes
• Wound-healing and tissue regeneration research

These research directions continue to support interest among laboratories working in regenerative biology and structural cell research.

Proper storage supports peptide integrity and consistent research outcomes.

Lyophilized (Unopened)

• Store at –20 °C for long-term stability
• Short-term storage at 2–8 °C is acceptable
• Keep vials sealed in original packaging
• Protect from light and moisture

Reconstituted Solution

• Store at 2–8 °C after reconstitution
• Use within 24–72 hours
• Avoid repeated freeze–thaw cycles
• Minimize temperature fluctuations

Visible changes in clarity, color, or particulate formation may indicate degradation and should be evaluated prior to continued research use.
