TB-500

$100.00

TB-500 is a synthetic peptide analogue of Thymosin Beta-4 (Tβ4), a naturally occurring protein that plays a vital role in cell structure and tissue repair.
In research models, TB-500 is studied for its ability to regulate actin polymerization, a fundamental process for cell migration, angiogenesis, and wound healing.

TB-500 contains a specific active fraction of the parent protein Thymosin Beta-4, known as the actin-binding domain (sequence: Ac-Ser-Asp-Lys-Pro-D-Phe-His-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu). Research indicates that this specific sequence is responsible for the peptide’s ability to sequester monomeric actin (G-actin), which is critical for maintaining the cellular cytoskeletal reservoir necessary for cell motility and rapid tissue remodeling.

Unlike the full-length Thymosin Beta-4 protein (43 amino acids), TB-500’s lower molecular weight allows for greater tissue penetration and ease of handling in laboratory settings. Scientific studies primarily focus on its potential to promote endothelial cell migration, reduce inflammation, and accelerate the repair of damaged skeletal muscle and connective tissues in various injury models.

Product Specifications:

  • Sequence: Ac-Ser-Asp-Lys-Pro-D-Phe-His-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu (Note: Often simplified in literature to LKKTETQ, but research products vary; verify if it’s the full Tβ4 or the fragment. Most “TB-500” sold is the synthetic Tβ4 analog).

  • Molecular Formula: C212H350N56O78S (for full Tβ4) or C38H68N10O14 (for fragment) – Standard “TB-500” usually refers to the synthetic Tβ4 sequence in research markets.

  • Molecular Weight: ~4963 g/mol (if full Tβ4)

  • CAS Number: 77591-33-4

  • Purity: ≥99% (HPLC)

  • Form: Lyophilized White Powder

Storage & Handling:
Lyophilized TB-500 is stable at room temperature for short periods but should be stored at -20°C for long-term preservation. Upon reconstitution with bacteriostatic water, the peptide should be kept at 4°C and used within 8 days to 2 weeks to ensure maximum viability, as it degrades faster than some other peptides in solution.

FAQ

What is the relationship between TB-500 and Thymosin Beta-4?
Thymosin Beta-4 is a naturally occurring protein found in high concentrations in platelets and wound fluid. TB-500 is a synthetic version of this protein (or a specific active fragment of it) designed for research purposes to mimic the natural regenerative properties of Tβ4.

How does TB-500 work in cell cultures?
The peptide functions by binding to actin, a cellular building block. This interaction promotes “actin sequestration,” keeping actin available for the rapid assembly of new filaments. This process is essential for cells to move (migrate) to sites of injury and repair tissue.

Is TB-500 systemic or local in research applications?
Research suggests that TB-500 has systemic effects, meaning it can circulate throughout the body to reach sites of injury, unlike some growth factors that only act locally. Its low molecular weight facilitates this biodistribution in animal models.

Does TB-500 promote muscle growth?
While often associated with muscle recovery, TB-500’s primary mechanism in research is tissue repair and regeneration (healing damaged fibers) rather than direct hypertrophy (growth of new muscle tissue) like anabolic agents. It is studied for its ability to reduce scar tissue formation and improve muscle fiber organization after injury.
