Overview
A synthetic fragment of Thymosin β4 investigated for actin regulation and cell-migration pathways in pre-clinical models.
TB-500 is studied for its actin-binding activity. In research models it sequesters G-actin and up-regulates actin expression, which is associated with increased cell migration, and it has been examined for a role in angiogenesis and cell-differentiation pathways.

Common questions
Research FAQ: eligibility, shipping, payment and returns
What is TB-500 studied for?
It is examined in non-clinical models for actin-binding activity, cell-migration markers, and angiogenesis-related signaling.
How does it differ from Thymosin β4?
TB-500 is a synthetic fragment representing the active actin-binding region of the full Thymosin β4 protein, supplied as a research reference material.
How is it supplied?
Each listing identifies the supplied format (lyophilized powder in a sealed vial) and storage conditions. Batch-specific documentation is shown when published. We do not provide reconstitution, dosing or administration guidance.
How is purity verified?
The product page shows the current batch documentation status. When a reviewed certificate is published, open the laboratory PDF for its reported methods and results. Only use analytical methods and identity results explicitly recorded for that batch. For other records, ask the research desk.
Who can order?
These are research-use-only materials sold to qualified researchers and institutions. They are not for human or veterinary use, consumption, or any diagnostic, therapeutic, cosmetic or food application.
