Thymosin β4 (TB-500) – vollständige Sequenz (1–43) / 5 mg

Beschreibung

Full-length actin-regulating peptide for tissue and cell signaling research

Thymosin β4 is a naturally occurring peptide found in many cell types and studied for how it supports cell movement, structure, and repair processes. This version is the full 43–amino acid sequence, which is the complete biological form used in research. It’s often chosen when researchers want a more accurate model of how the peptide behaves in natural cellular environments, rather than using shortened fragments. You’ll often see “TB-500” mentioned in the same context, but that term usually refers to shorter or undefined fragments. In controlled research settings, full-sequence Thymosin β4 (1–43) is the clearly defined compound.

Thymosin β4 (1–43) vs TB-500

Thymosin β4 (1–43):
Full-length 43 amino acid peptide
Naturally occurring endogenous sequence
Molecular weight ~4963 Da
Defined and reproducible research compound

TB-500:
Non-standardized naming term
Typically refers to shorter TB4 fragments
Variable sequence length (often ~17 amino acids)
Not equivalent to full-length Thymosin β4

→ For clarity and reproducibility in research contexts, full-sequence Thymosin β4 (1–43) is the superior compound.

Research applications (investigational)

Thymosin β4 (1–43) has been investigated in preclinical and experimental settings for its involvement in:

• Actin dynamics and cytoskeletal organization
• Cell migration and intracellular signaling pathways
• Tissue remodeling processes
• Angiogenesis-related mechanisms
• Inflammatory signaling modulation
• In vitro and in vivo wound-healing models
• Cardiac and dermal tissue research models

These areas reflect ongoing scientific interest in the peptide’s role in fundamental cellular processes rather than established applications.
