TB-500

TB-500 is a synthetic peptide fragment corresponding to the actin-binding region associated with thymosin beta-4. It is studied in preclinical research involving actin regulation, cell migration, tissue repair mechanisms, and related cellular processes.

The supplied TB-500 material is a 7-amino acid synthetic peptide with the sequence Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln (Ac-LKKTETQ). It is provided as a lyophilized powder with ≥99% HPLC purity for laboratory research.

What is TB-500?

TB-500 is a synthetic, shorter peptide designed around the actin-binding motif associated with thymosin beta-4.

The supplied product consists of seven amino acids and is identified by the sequence Ac-LKKTETQ. Research involving TB-500 examines cellular mechanisms associated with actin dynamics, cell migration, and tissue-repair processes.

It is important to distinguish TB-500 from full-length thymosin beta-4 (TB4). Full-length thymosin beta-4 is a naturally occurring 43-amino acid peptide, whereas the TB-500 material described here is a shorter synthetic fragment.

What is TB-500 studied for?

TB-500 is investigated in preclinical research focused on actin-associated cellular processes and tissue-repair mechanisms.

Key research areas include:

• Actin dynamics: Research examines the peptide's relationship with actin regulation and cellular structural processes.
• Cell migration: Studies investigate mechanisms involved in cell movement and migration during experimental tissue-repair models.
• Tissue repair: TB-500 has been explored in preclinical models involving tissue-repair processes.
• Wound-healing research: Experimental research has examined related mechanisms in dermal and other tissue models.
• Muscle and connective-tissue research: Studies investigate cellular responses associated with tissue injury and repair.
• Inflammatory research: TB-500 has also been explored in experimental models involving inflammatory and injury-related processes.

These areas describe preclinical research, not established clinical applications. Experimental findings should not be interpreted as evidence that TB-500 is a treatment for wounds, injuries, inflammation, or other medical conditions.

TB-500 vs. Thymosin beta-4

TB-500 is often discussed alongside thymosin beta-4, but the two should not be treated as identical materials.

TB-500 is described here as a 7-amino acid synthetic fragment with the sequence Ac-LKKTETQ. In contrast, full-length thymosin beta-4 is a naturally occurring 43-amino acid peptide.

The distinction matters when evaluating research materials because molecular length, sequence, and structure are fundamental to identifying a peptide correctly.

For laboratory work, researchers should verify the exact peptide sequence and product specifications rather than assuming that TB-500 and full-length thymosin beta-4 are interchangeable.

What makes this TB-500 different?

The defining characteristics of this TB-500 research material are its short 7-amino acid sequence, synthetic peptide structure, and relationship to the actin-binding region associated with thymosin beta-4.

The product has a reported molecular formula of C38H68N10O14, molar mass of 889.02 g/mol, and stated purity of ≥99% by HPLC.

These specifications provide useful reference points for researchers comparing TB-500 with other thymosin-related research materials.
