TB-500 10 MG

$80.00

TB-500 10 MG is a research peptide corresponding to the synthetic active fragment of thymosin beta-4, a naturally occurring actin-sequestering protein. The fragment retains the actin-binding domain responsible for regulating G-actin monomer availability, a function central to cytoskeletal dynamics, cell migration, and motility. Because of this mechanism, TB-500 is widely used as a reference tool in studies of actin regulation at the molecular and cellular level. In the laboratory, researchers study TB-500 in in-vitro and preclinical tissue-repair models to examine cell migration, proliferation assays, and wound-closure dynamics in cultured systems. It is also investigated in angiogenesis research, where its influence on endothelial cell behavior and capillary-formation assays is characterized. Further work addresses its actin-sequestering kinetics, peptide stability, and reproducibility across analytical assays. Peptiva Research Labs supplies it as a research-grade reference compound, HPLC-verified with a COA available. For Research Use Only, not for human or veterinary use.

Frequently asked questions

What is TB-500?
TB-500 is the synthetic active fragment of thymosin beta-4, retaining the actin-binding domain that regulates G-actin availability. This makes it a useful tool for studying cytoskeletal dynamics and cell migration. It is provided as a research compound only.
What do labs study TB-500 for?
Researchers use it in vitro and in preclinical models to investigate actin regulation, cell migration and proliferation, tissue-repair assays, and angiogenesis. Endothelial cell behavior in capillary-formation assays is a common focus. All applications are laboratory-based and mechanistic.
What is the purity and how is it stored?
Each lot is HPLC-verified with purity documented on the accompanying COA. Store the lyophilized vial cold and protected from light, and after reconstitution with a suitable diluent keep aliquots frozen to limit freeze-thaw cycles. This preserves peptide integrity for in-vitro work.
