THYMOSIN BETA-4 FRAGMENT · RESEARCH HUB

TB-500 Peptide Research Hub — Thymosin Beta-4 Tissue-Repair Studies

TB-500 is a synthetic peptide corresponding to the active region of naturally occurring Thymosin Beta-4 — one of the most abundant actin-sequestering proteins in mammalian cells. It is widely studied in tissue-repair, angiogenesis and cell-migration research.

What this hub covers

  • Actin G-to-F sequestering mechanism
  • Cell migration and endothelial proliferation literature
  • Cardiac, dermal and corneal tissue-repair models
  • Comparisons and synergy with BPC-157
  • Reconstitution and storage for research use

TB-500 research FAQ

What is TB-500?
TB-500 is a synthetic peptide fragment of Thymosin Beta-4 (Tβ4), a 43-amino-acid actin-sequestering protein. The fragment retains the actin-binding region responsible for cell migration and tissue-repair signalling in the published literature.
How does TB-500 differ from BPC-157?
TB-500 acts via actin sequestration and cell migration; BPC-157 acts primarily through VEGFR2 and nitric-oxide-mediated angiogenesis. The two are commonly studied together for complementary mechanisms — see the BPC-157 vs TB-500 comparison.
What models is TB-500 most cited in?
Cardiac repair after ischaemia, corneal wound healing, dermal repair and skeletal muscle regeneration are among the most-cited models. The TB-500 research overview compiles representative citations.
How is TB-500 stored?
Lyophilized TB-500 is stable at 2–8 °C protected from light. After reconstitution with bacteriostatic water, refrigerate and use within the COA's documented window.
