TB-500 (Thymosin Beta-4) 20mg

Within Europe this product is supplied including bacteriostatic water; outside Europe only the peptide vial is provided.

For research use only — not for human or veterinary use.

Product Overview

TB-500 is a synthetic research peptide corresponding to a biologically active fragment of Thymosin Beta-4. It is studied in controlled laboratory environments for its involvement in cytoskeletal organisation, cellular migration modelling and peptide-mediated regenerative signalling pathways. This lyophilized 20 mg preparation is supplied in a sealed research vial and supports reproducible in vitro experimentation.

Peptide Overview

Thymosin Beta-4–derived peptides have been investigated in laboratory research since the late twentieth century for their interaction with actin-binding mechanisms and cellular structural regulation. TB-500 represents a stabilised research analogue frequently utilised in experimental models examining cellular response dynamics and peptide-driven pathway modulation.

Historical Background and Scientific Context

Research into thymosin-related peptides expanded significantly during the 1980s and 1990s as scientists investigated endogenous peptides involved in cellular structure and regulatory signalling. TB-500 has since been incorporated into preclinical research frameworks examining actin dynamics, migration pathways and regenerative modelling under controlled experimental conditions.
