TB-500 Research Peptide — 5mg Lyophilized
TB-500 is a synthetic analog of the naturally occurring peptide Thymosin Beta-4 (Tβ4). It represents a key actin-sequestering peptide that has been widely studied in the context of cellular migration, differentiation, and angiogenesis in preclinical research models.
The molecular formula of TB-500 is C212H350N56O78S (when studied as the full Thymosin Beta-4 fragment). In vitro studies have examined its interaction with actin monomers and downstream pathways including Lim kinase and cofilin phosphorylation. Published research has also explored its effects in various wound-healing, cardiac, and neural cell culture models.
