Frequently Asked Questions

What is TB-500 (Thymosin β4 Fragment)?

TB-500 is a synthetic peptide modeled after a segment of the natural protein Thymosin Beta-4. It is used in preclinical research focused on cell migration, angiogenesis, and tissue recovery. Each vial contains research-grade TB-500 with verified purity and identity.

How is TB-500 supplied?

Each vial contains 5 mg of lyophilized TB-500 peptide powder with no fillers or excipients. The product is supplied sterile-sealed and intended exclusively for laboratory research and in-vitro studies.

What quality verification does TB-500 have?

Every batch of TB-500 is independently tested by BT Labs using HPLC analysis and verified at ≥ 99 % purity. Certificates of Analysis (COAs) are batch-specific and available on the product page for full transparency.

How should TB-500 be stored and handled?

Keep lyophilized vials stored at 2–8 °C in a dark, dry environment. For long-term storage, freezing below 0 °C is recommended. After reconstitution, refrigerate at 2–8 °C and avoid multiple freeze-thaw cycles.
