TB500 Fragment

Research & Reconstitution Information

Thymosin Beta-4 is a naturally-occurring 43-amino-acid protein; 'TB-500' is a product name under which commercial peptide products have been shown analytically to contain a short synthetic fragment corresponding to its actin-binding region. Research on the protein and this fragment has studied actin-sequestering activity that regulates cytoskeletal dynamics and cell migration, with animal-model investigation into dermal wound-healing, angiogenesis and cardiac tissue repair. All cited evidence is preclinical — rodent, chick or cell-culture studies, not human clinical trials. Reconstitute with bacteriostatic water, swirl gently (do not shake), and store unreconstituted vials at 2-8°C short-term or -20°C for long-term storage. Refrigerate (2-8°C) once reconstituted. For laboratory research purposes only.

Certificate of Analysis

All products are independently tested by accredited third-party laboratories. Results confirm identity, purity, and potency.

How to Reconstitute

1. 1.Clean the vial top with an alcohol swab, then slowly release solvent along the inside wall of the vial — don't squirt directly onto the powder.
2. 2.Let it dissolve on its own for a few minutes. Swirl gently if needed — do not shake.
3. 3.Refrigerate (2-8°C) once reconstituted.
