TB-500

TB-500 is a synthetic peptide fragment of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino acid protein. TB-500 specifically represents the active region responsible for actin binding and cell migration properties studied in tissue repair research. It is more stable and cost-effective than full-length Tβ4 for research applications.

Reconstitute with bacteriostatic water using sterile technique. For a 5mg vial, add 2mL of BAC water for a 2.5mg/mL concentration. Inject slowly along the vial wall and swirl gently. Reconstituted TB-500 is stable at 39°F (4°C) for up to 7 days.

Lyophilized TB-500 maintains ≥95% stability for 24+ months when stored at -4°F (-20°C). After reconstitution, store at 39°F (4°C) and use within 7 days for optimal activity.

Every batch is independently tested by accredited third-party laboratories with full Certificates of Analysis (COA) available on request. We guarantee ≥98% purity across our catalog, use pharmaceutical-grade lyophilization, and ship with cold-chain packaging to preserve compound integrity. Our research-grade peptides are manufactured under strict GMP-compliant conditions, ensuring consistency and reliability that many competitors cannot match.

Yes. We can provide HPLC, mass spectrometry, endotoxin testing, and amino acid analysis reports for any product.
