TB-500 5 mg (Thymosin Beta-4 Fragment)

Overview

TB-500 is a synthetic research peptide derived from the biologically active region of Thymosin Beta-4 (TB4), a naturally occurring protein involved in a variety of cellular processes. While TB-500 is not identical to the full-length TB4 protein, it has become a widely studied research peptide in laboratory investigations exploring cell migration, cytoskeletal organization, and tissue biology.

Due to its stability and research applications, TB-500 is frequently investigated in experimental models examining peptide signaling, cellular responses, and molecular biology.

NextCell Peptides supplies Research Grade TB-500 5 mg as a high-purity lyophilized peptide manufactured under controlled quality standards. Each vial is clearly labeled to support product identification and laboratory traceability.

What Is TB-500?

TB-500 is a synthetic peptide derived from a biologically active region of the naturally occurring protein Thymosin Beta-4 (TB4).

Thymosin Beta-4 is found in many tissues throughout the body and has been extensively studied for its role in normal cellular processes, including cell migration, cytoskeletal dynamics, and tissue organization.

TB-500 was developed as a research peptide to investigate selected biological activities associated with Thymosin Beta-4 under controlled laboratory conditions. Although related, TB-500 should not be considered identical to the native TB4 protein.

Common Laboratory Applications

TB-500 is frequently investigated in laboratory research involving:

• Cell migration

• Cytoskeletal organization

• Molecular biology

• Peptide signaling

• Tissue biology

• Cell culture research

• Experimental peptide pharmacology

• Regenerative biology research

• Protein interaction studies

• Laboratory peptide research

The specific application depends on the laboratory protocol and experimental objectives.

Why TB-500 Is Studied

TB-500 is studied because it represents a biologically active fragment derived from Thymosin Beta-4 and provides researchers with a practical model for investigating peptide function under controlled laboratory conditions.

Ongoing research continues to explore its biochemical properties, cellular interactions, and potential relevance in experimental models of tissue biology and molecular signaling.

Storage & Handling

Store refrigerated at 2–8°C.

For extended storage, keep frozen at −20°C.

Protect from moisture, excessive heat, and direct light.

After reconstitution, handle using appropriate laboratory procedures and avoid repeated freeze–thaw cycles whenever possible to help maintain sample integrity.

Choosing Research Grade TB-500

When evaluating research peptides, consider factors beyond the reported purity.

Important considerations include:

• HPLC purity testing

• Batch consistency

• Product labeling

• Certificate of Analysis (COA) availability

• Manufacturing standards

• Appropriate storage recommendations

• Packaging integrity

These factors help support reliable laboratory workflows and reproducible research.
