Product Description

TB-500 is a synthetic peptide fragment of Thymosin Beta-4, a naturally occurring peptide involved in cell structure and movement. It is widely investigated in tissue repair and regenerative research.

Mechanism of Action:

• Promotes cell migration to sites of injury

• Enhances angiogenesis (formation of new blood vessels)

• Reduces inflammation in damaged tissues

• Supports cell survival under stress conditions

• Regulates actin, a key protein in cell structure and movement

Research Applications:

• Soft tissue repair studies (muscle, tendon, ligament)

• Wound healing research

• Angiogenesis investigations

• Inflammatory response modulation

• Regenerative medicine preclinical studies

TB-500 is typically administered via subcutaneous or intramuscular injection in research models. Dosing protocols vary by study design and should be established by the investigating institution.

Quality Assurance

• Manufactured under controlled conditions

• Purity verified by HPLC (≥99%)

• Mass spectrometry confirmation for molecular identity

• Certificate of Analysis (CoA) provided with each shipment

• Residual solvent analysis available upon request
