TB-500 5mg
TB-500 (Thymosin Beta-4) is a 43 amino acid synthetic peptide sequence. In animal models, Thymosin Beta-4 has been shown to improve blood vessel growth, regulate wound healing, decrease inflammation, and reduce oxidative damage in the heart and central nervous system. It has a role in tissue protection, repair, regeneration, and remodeling of injured or damaged tissues, and is of active interest in longevity and cellular senescence research.

About TB-500 5mg
TB-500 is the active domain of Thymosin Beta-4 (TB-4), with a primary role as an actin binding protein. Its amino acid sequence is Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser. Research demonstrates TB-500 encourages nervous system tissue repair and remodeling by activating oligodendrocytes, is a potent stimulator of VEGF expression for capillary growth, promotes hair growth through increased hair follicle numbers and grouping, enhances antibiotic effects synergistically when combined with ciprofloxacin, promotes cardiovascular recovery through collateral blood vessel growth and reduced fibrosis following heart attack, and enhances autophagy as a protective mechanism against neurodegenerative diseases. This 5mg vial provides material for tissue repair and regenerative biology research.
Storage and reconstitution
Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Lyophilized powder is stable at room temperature for shipping and short-term storage.
Shipping within Canada
Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
