Description
TB-500 is a thymosin beta-4–derived research peptide used in controlled in-vitro studies of cell migration, cytoskeletal dynamics, and extracellular-matrix signalling under non-clinical laboratory conditions.
TB-500 (Thymosin Beta-4 Fragment)
This peptide is selected in model systems to explore pathways related to actin modulation, tissue biology, and assay readouts for cell motility and matrix interaction. All investigations are performed in laboratory settings only. For laboratory research only. Not for human use.
TB-500 Key features
Thymosin beta-4 fragment for in-vitro studies of cell migration and ECM-related pathways. Supplied as a lyophilised solid for stability and straightforward storage. Unit size: 5 mg per vial. Each batch released only after stringent quality checks.
Specifications
Product name: TB-500 Synonyms: Thymosin beta-4 fragment; TB4 fragment peptide Class: Peptide fragment (research use) Form: Lyophilised powder Appearance: White to off-white solid Note: Identity and exact properties may vary with salt/counter-ion and hydration state.
Handling & storage
Storage (dry): Keep vials protected from light and moisture. Reconstitution: Bring vial and diluent to room temperature. Reconstitute with Bacteriostatic Water 10 ml. Swirl gently — do not vortex. After reconstitution: Store at 2–8 °C, protect from light, use aliquots to reduce handling, and avoid repeated temperature cycling. Compatibility: Use only within research protocols that follow your lab’s SOPs and local regulations.

About TB-500 in research
Researchers use TB-500 to interrogate assay readouts associated with cytoskeletal organisation, cell migration, and extracellular-matrix interactions in model systems. These studies focus on molecular mechanisms and pathway mapping, not clinical use.
Synthesis & quality
Manufactured via controlled, validated peptide-synthesis processes to deliver high purity and lot-to-lot consistency. Each batch undergoes identity, purity, and appearance checks before release.
