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.

Handling & Storage Guidelines

Unreconstituted (Lyophilised) Storage:
Store at −20°C for long-term preservation. Short-term storage at 2–8°C is acceptable if intended for use within 1–3 months.

Reconstituted Storage:
After reconstitution, store at 2–8°C and use within 3–6 weeks. Stability may vary depending on solvent selection and laboratory handling conditions.

Avoid repeated freeze–thaw cycles. Protect from excessive agitation, heat, and direct light exposure.
