TB-500 Peptide (Thymosin Beta-4) 10mg for Laboratory Research
TB-500 is a synthetic peptide corresponding to the active region of thymosin beta-4 (TB4), a naturally occurring actin-sequestering protein. It is used in preclinical laboratory work as a reference compound in studies of cell migration, tissue repair signaling and inflammation resolution, and appears in literature under the names TB-500, TB-4 and thymosin beta-4 peptide.
Real Peptides supplies TB-500 as a lyophilized powder in a 10mg multi-dose vial. Identity and purity are verified by an independent third-party laboratory, and the certificate of analysis for the current lot is published on the lab results page so it can be reviewed before purchase rather than requested afterward. Orders ship from US facilities in Florida and California within 24 hours. Sold strictly for laboratory research use only.

TB500 (Thymosin Beta-4) is a synthetic 43-amino-acid peptide fragment used in preclinical models to explore tissue repair, cell migration, and inflammation resolution. In cell-culture wound-closure assays and rodent injury models, TB-500 accelerates fibroblast migration, modulates cytokine profiles, and supports angiogenic signaling. Each 10 mg vial is HPLC-verified to ≥ 99% purity, endotoxin-screened (< 0.1 EU/mg), and formulated for laboratory research.
What is TB-500?
TB-500, also called TB500 or Thymosin Beta-4 peptide, is a synthetic fragment of the naturally occurring Thymosin β4 protein. It plays a key role in actin-binding, cell-migration, and repair signaling. In research contexts, TB-500 is applied to both in vitro and in vivo models to dissect pathways of tissue regeneration, angiogenesis, and inflammation resolution.
Why Choose TB-500 Peptide?
Researchers select TB-500 when they need a versatile tool for modeling wound healing, vascular growth and anti-inflammatory effects in controlled experiments. Its proven effect in accelerating cell migration and promoting capillary formation—coupled with ≥ 99% purity—ensures reproducible, high-quality data for regenerative-medicine and tissue-repair studies.
What Sets TB-500 Apart?
Unlike broader growth-factor agents, TB-500 peptide offers precise modulation of both cytoskeletal dynamics and angiogenic signaling via its actin-binding properties. Its dual action on cell migration and inflammation resolution, plus demonstrated stability in solution, makes TB-500 the go-to peptide for high-resolution studies of tissue repair and regenerative pathways.
