TB-500 5mg – 3ml Vial
(Thymosin Beta-4 Fragment Research Peptide)
Product Overview
TB-500 is a synthetic fragment derived from the naturally occurring peptide Thymosin Beta-4 (Tβ4), a protein involved in actin regulation within cells. In controlled in-vitro and pre-clinical research systems, TB-500 is utilised to investigate cytoskeletal dynamics and peptide-mediated cellular signalling mechanisms.
In laboratory research environments, TB-500 is commonly studied for:
- Actin polymerisation and depolymerisation regulation
- Cellular migration pathway models
- Cytoskeletal signalling mechanisms
- Angiogenesis-associated pathway research
- Extracellular matrix interaction models
- Peptide-mediated tissue remodelling research
Due to its structural characteristics and origin from Tβ4, TB-500 is frequently selected for mechanistic studies involving cellular movement and actin-associated processes.
Supplied in lyophilised form to preserve peptide integrity and analytical stability prior to reconstitution.
