What is TB-500?
TB-500 (Thymosin Beta-4 active fragment) in oral tablet form for GI absorption studies. The actin-binding LKKTETQ heptapeptide domain of Thymosin Beta-4, responsible for G-actin sequestration, cell migration promotion, angiogenesis, and anti-inflammatory cytokine modulation.
Oral formulation enables gut-first-pass pharmacokinetic studies compared to parenteral administration. Research use only.
