TB-500

TB-500 - 10 mg

TB-500 is the designation for a synthetic peptide associated with the research environment of Thymosin β4. In scientific analyses, TB-500 has been identified as an N-terminally acetylated fragment of amino acids 17–23 of Thymosin β4 with the sequence Ac-LKKTETQ. Since the designation is not always used consistently on the market, the exact molecular identity should be confirmed based on the specific batch and analysis documentation.

The product offered contains a declared content of 10 mg and is intended exclusively for controlled scientific, analytical, and biochemical research purposes.

Product Data

• Designation: TB-500
• Declared Content: 10 mg
• Product Form: lyophilized peptide material
• Packaging: 1 sealed vial
• Product Group: synthetic research peptide
• Use: exclusively scientific and analytical research
• Peptide Sequence: will be added after checking batch documentation

Scientific Background

Thymosin β4 is a naturally occurring peptide of 43 amino acids that, among other things, interacts with actin and is studied in basic research in connection with cell migration, cytoskeletal dynamics, and various tissue models.

Scientific research areas include, for example:

• Interactions with actin and the cellular cytoskeleton
• Cell migration and cell survival
• Angiogenesis and vascular models
• Inflammation and apoptosis processes
• Experimental wound and tissue models
• Comparative study of Thymosin-β4 fragments

Important: Research results on the complete Thymosin-β4 molecule cannot be automatically transferred to the shorter TB-500 fragment. TB-500 and complete Thymosin β4 should therefore not be presented as identical substances on the product page. Furthermore, the published findings predominantly originate from preclinical or experimental research models.

Molecular Identity

Before publication, it should be clarified based on the supplier's certificate whether the product actually contains the following specification:

• Designation: TB-500
• Sequence: Ac-LKKTETQ
• Assignment: acetylated fragment 17–23 of Thymosin β4

If your supplier delivers complete Thymosin β4 with 43 amino acids instead, we must not simply treat it as the same product.

Quality and Documentation
