Description

Buy TB-500 — Thymosin Beta-4 Fragment Research Peptide

Researchers looking to buy TB-500 for laboratory study will find this synthetic peptide corresponds to an active region of Thymosin Beta-4 (TB-4), a naturally occurring 43-amino acid regulatory protein present in nearly all human and animal cells. TB-500 is one of the most extensively researched peptides in the tissue repair, angiogenesis, and cellular migration categories. Because of its compact structure and binding affinity for actin, it has been used extensively as a research tool for studying cellular repair mechanics across multiple tissue types.

Mechanism of Action

TB-500 has been investigated in published research for activity across several biological pathways, including:

  • Actin regulation — interaction with G-actin and influence on cytoskeletal organization
  • Cell migration — research on keratinocyte, endothelial, and fibroblast movement during repair processes
  • Angiogenesis — formation of new blood vessels and capillary networks
  • Anti-inflammatory signaling — modulation of inflammatory cytokine pathways in preclinical models
  • Tissue and soft-structure research — investigations into muscle, tendon, ligament, and dermal repair models

Because of its compact structure and binding affinity for actin, TB-500 has been used extensively as a research tool for studying cellular repair mechanics across multiple tissue types.

Research Applications

TB-500 is widely used in many research contexts including:

  • Soft tissue and musculoskeletal repair studies
  • Cardiac and vascular repair research models
  • Dermal and wound-healing investigations
  • Angiogenesis and endothelial migration research
  • Comparative studies alongside BPC-157 and other repair-pathway peptides

Product Specifications

  • Compound: TB-500 (Thymosin Beta-4 Fragment)
  • Form: Lyophilized white powder
  • Purity: ≥99% (verified by HPLC and mass spectrometry)
  • Available sizes: 10mg
  • Third-party tested: Certificate of Analysis available on request

Reconstitution & Storage

Lyophilized TB-500 should be stored at -20°C for long-term stability and protected from light. Once reconstituted with bacteriostatic water, the solution should be refrigerated at 2–8°C and used within the timeframe indicated on the product COA. Avoid repeated freeze-thaw cycles, as they can degrade peptide integrity.

Shipping & Handling

All orders are shipped with temperature-controlled packaging to preserve peptide integrity. Domestic orders typically arrive within 2–4 business days. Tracking is provided on every order.

Storage & Handling

Storage & Handling

Proper storage and handling are essential to maintaining peptide stability and ensuring the integrity of your research material.

Storage Recommendations

Lyophilized peptides should be stored at -20°C for long-term preservation. For short-term storage of up to 30 days, refrigeration between 2-8°C is acceptable. Reconstituted peptides should always be refrigerated and used within 30 days.

Avoid the following:

Direct sunlight or UV exposure Repeated freeze-thaw cycles Temperature fluctuations Storage at room temperature beyond brief handling periods

Reconstitution Best Practices

Allow vials to reach room temperature before opening to prevent condensation. Use bacteriostatic water as the diluent for most peptides, injecting slowly along the side of the vial. Gently swirl to dissolve — do not shake. Allow the solution to fully dissolve before drawing for research use.

Shelf Life

Lyophilized peptides maintain potency for up to 24 months when stored properly at -20°C. Reconstituted solutions should be used within 30 days for optimal research results.
