Scientific Overview
TB-500 is a synthetic peptide modeled after a naturally occurring region of thymosin beta-4, a protein involved in cellular migration and tissue biology. It is widely researched for its role in regenerative and cellular processes.
Mechanism
TB-500 corresponds to a region of thymosin beta-4 and is researched for effects on actin sequestration, cell migration, and cytoskeletal dynamics in regenerative biology studies.
Areas of Active Scientific Research
Researchers continue to study TB-500 for its potential influence on cell migration, angiogenesis, tissue remodeling, cytoskeletal organization, and regenerative mechanisms, contributing valuable insights into tissue biology and repair pathways.

Purity
Target purity ≥99% by HPLC. The binding value for any vial is the result on that lot’s Certificate of Analysis.
Batch documentation
Contact support with your order or batch number to request the analytical record for a specific lot, or use COA Verification.
support@primelabs.bioWhat a COA demonstrates
Batch-specific identity verification, purity by validated analytical methods (e.g. HPLC), and third-party laboratory testing records for the referenced lot.
What a COA does not demonstrate
Clinical efficacy, safety for human or veterinary use, or suitability for any application outside qualified laboratory research.
Quality Assurance
Each lot is supported by batch-specific analytical documentation used to verify identity and purity. The Certificate of Analysis is the binding record for that vial.
