TB-500 – Thymosin Beta-4 Fragment for Research

TB-500 is a synthetic research peptide corresponding to the N-acetylated 17–23 fragment of human thymosin beta-4. Its compact seven-amino-acid sequence, Ac-LKKTETQ, represents an important region associated with actin-related cellular processes. This clearly defined molecular structure makes TB-500 particularly relevant for professional laboratory studies involving actin dynamics, cytoskeletal organisation, endothelial-cell behaviour, cellular migration and peptide structure–activity relationships. TB-500 is supplied as a premium lyophilised research material in a securely sealed vial with clear batch information, professional packaging and fast order processing from Peptides Divas.

What Is TB-500?

TB-500 is a synthetic heptapeptide identified as the N-terminally acetylated 17–23 fragment of human thymosin beta-4. Its amino-acid sequence is: Ac-Leu–Lys–Lys–Thr–Glu–Thr–Gln The abbreviated sequence is: Ac-LKKTETQ TB-500 contains the central actin-binding motif associated with thymosin beta-4, but it is a separate and much smaller research compound than full-length thymosin beta-4. This distinction is important because TB-500 and complete thymosin beta-4 have different molecular sizes, analytical profiles and research characteristics.

TB-500 Versus Thymosin Beta-4

TB-500 is often incorrectly described as being identical to thymosin beta-4. Full-length thymosin beta-4 is a naturally occurring 43-amino-acid protein involved in actin regulation. TB-500 is a synthetic seven-amino-acid fragment derived from one region of that protein.

Researchers should confirm the exact sequence using the product label and batch-specific analytical documentation.

Actin-Related Research

Actin is an essential cellular protein involved in maintaining cell structure, movement and cytoskeletal organisation. The LKKTETQ region is associated with the actin-binding domain of thymosin beta-4, making TB-500 relevant for research involving:

• Processus cellulaires liés à l'actine
• Organisation du cytosquelette
• Cell shape and structural dynamics
• Actin polymerisation models
• Actin-binding interactions
• Cellular movement
• Focal adhesion pathways
• Cell-to-matrix communication
• Comparative actin-binding research
• Interactions peptide-protéine

The exact behaviour of the isolated TB-500 fragment may differ from the activity of complete thymosin beta-4.

Cellular Migration Research

Cellular migration is a complex process involving actin remodelling, cytoskeletal organisation, adhesion proteins and extracellular signals. TB-500 may be relevant for controlled laboratory research involving:

• Migration cellulaire
• Endothelial-cell movement
• migration des fibroblastes
• Réorganisation du cytosquelette
• Adhésion cellulaire
• Cell spreading
• Actin-dependent movement
• relations concentration-réponse
• Criblage comparatif de peptides
• Migration-assay development

These research areas describe experimental cellular pathways and do not represent guaranteed biological or therapeutic outcomes.

Endothelial-Cell Research

Endothelial cells form the inner lining of blood vessels and are frequently used in laboratory research involving migration, adhesion and vascular signalling. Potential TB-500 research applications include:

• Endothelial-cell migration
• Endothelial-cell adhesion
• Tubule-formation models
• Cell-sprouting assays
• Vascular signalling
• Angiogenesis-associated pathways
• Organisation du cytosquelette
• interactions cellule-matrice
• Comparative endothelial assays
• Molecular-response analysis

Research involving thymosin beta-4 and its actin-binding region has examined endothelial migration and vessel-sprouting mechanisms in preclinical models.

Cytoskeletal Research

The cytoskeleton is a dynamic network that supports cell shape, intracellular transport, movement and division. TB-500 may be useful for studies examining:

• Actin-filament organisation
• Cytoskeletal remodelling
• Cellular polarity
• Cell-shape changes
• Intracellular transport
• Migration cellulaire
• Adhesion-complex formation
• Mechanical cellular responses
• Actin-associated protein interactions
• Comparative cytoskeletal models

Its compact sequence offers researchers a convenient way to study a specific thymosin beta-4-derived region without using the entire parent protein.

Recherche sur la structure des peptides

The small and clearly defined structure of TB-500 makes it suitable for peptide chemistry and structure–activity research. Potential research areas include:

• Synthetic heptapeptide characterisation
• N-terminal acetylation
• Stabilité des peptides
• Dégradation enzymatique
• Peptide metabolite identification
• relations structure-activité
• Amino-acid sequence analysis
• Modélisation moléculaire
• Interactions peptide-protéine
• Comparative fragment research

Researchers may compare TB-500 with full-length thymosin beta-4, non-acetylated LKKTETQ or shorter metabolites to examine how molecular modifications affect analytical and cellular behaviour.

Metabolite Research

Analytical research has identified several shorter TB-500-related metabolites, including:

• Ac-LKKTE
• Ac-LKK
• Ac-LK
• Ac-L

These fragments may be studied in relation to:

• Dégradation des peptides
• Metabolic stability
• Microsomal metabolism
• Identification des fragments
• Analytical detection
• Activité peptidique comparative

Les concentrations exactes, les contrôles et les procédures analytiques doivent être établis par le laboratoire qualifié qui effectue la recherche.

Recherche analytique

TB-500 is suitable for professional analytical applications involving:

• Chromatographie liquide à haute performance
• chromatographie liquide-spectrométrie de masse
• Confirmation de l'identité du peptide

• Identification des métabolites
• Profilage de la dégradation
• Évaluation de la solubilité
• Comparaison des matériaux de référence
• Développement de méthodes analytiques
• Comparative peptide-fragment analysis

Because TB-500 is a short acetylated peptide, analytical procedures should be validated specifically for Ac-LKKTETQ.
