- 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.
