Foundational Scientific Overview

TB-500 (5mg) is a prominent subject within the field of cellular motility, actin sequestration, and angiogenesis research. Originally synthesized as a synthetic fractional active domain of the naturally occurring protein Thymosin Beta-4, it has become a staple for researchers examining endothelial cell differentiation and the structural remodeling of damaged tissues.

At 4 Amino Labs, we provide this compound in a stabilized lyophilized powder to ensure experimental reproducibility. By maintaining rigorous measurement standards, we provide the consistency required for longitudinal data integrity. This compound is frequently cited in peer-reviewed literature due to its well-documented low molecular weight, which allows for exceptional tissue penetrability, and its primary binding affinity for G-actin monomers.

Analytical Composition & Purity Standards

  • Chemical Formula: C212H350N56O78S 
  • Physical State: White Lyophilized Solid 

Our TB-500 (5mg) undergoes a multifaceted verification process. Each batch is subjected to independent High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to ensure a purity threshold of ≥ 99%. This analytical rigor ensures the absence of residual solvents, heavy metals, or cross-contaminants, providing a stable baseline for your in-vitro or pre-clinical models.

Investigational Pathways

Researchers utilizing TB-500 (5mg) typically focus on the following biochemical mechanisms:

  • Actin Regulation: Evaluating the compound’s ability to sequester G-actin and prevent its polymerization into F-actin, maintaining cellular fluidity.
  • Angiogenesis: Observing the formation of new blood vessels from pre-existing microvascular networks in in-vitro assays.
  • Anti-fibrotic Action: Mapping the flux of collagen deposition and the inhibition of excessive scar tissue formation in cellular injury models.
  • Myocyte Survival: Investigating the agent’s cytoprotective role against induced ischemia or hypoxic stress in cardiac or skeletal muscle cells.

Laboratory Handling & Stability Protocol

To maintain the molecular integrity of TB-500 (5mg), the following storage parameters are recommended:

  • Thermal Regulation: Store in a controlled, cool, and desiccated environment. Reconstituted peptides must be refrigerated.
  • Photostability: Protect from direct UV exposure; storage in an opaque container or dark cabinet is advised to prevent photodegradation.
  • Hygroscopic Prevention: Ensure the seal is hermetic after every withdrawal to prevent moisture absorption and clumping.
  • Contamination Control: Use sterilized instruments and work within a laminar-flow hood, when possible, to maintain sample sterility.
