Description

Thymosin β4 (1–43) is a full-length endogenous peptide widely studied for its role in actin binding, cell migration, and tissue remodeling processes. It is present in most eukaryotic cells and is considered the biologically complete form of the molecule.
This product represents the full sequence (1–43 amino acids), in contrast to commonly marketed fragments such as TB-500. Full-length Tb4 (43 amino acids) is structurally distinct from shorter fragments and is studied for its role in actin regulation and cellular repair mechanisms.

Thymosin β4 (1–43) vs TB-500

Thymosin β4 (1–43):
Full-length 43 amino acid peptide
Naturally occurring sequence
Molecular weight ~4963 Da
Complete structural form used in research

TB-500:
Non-standardized term
Typically refers to synthetic fragments of TB4
Shorter sequences (often ~17 aa)
Does not represent 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 cellular signaling pathways
Tissue remodeling processes
Angiogenesis-related mechanisms (formation of new blood vessels)
Inflammatory signaling modulation
Wound healing models in vitro and in vivo
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.
