What is TB-500?

TB-500 acts as a primary G-actin sequestering molecule in mammalian cells. By regulating actin polymerization, it facilitates rapid cell motility to sites of injury, promoting angiogenesis, dermal wound closure, and muscular tissue repair.

Biological Mechanism

Binds monomeric actin to facilitate cytoskeletal remodeling, upregulates endothelial cell migration, and downregulates inflammatory cytokine cascades in damaged tissues.
