TB-500 2mg is a small-format vial of full-length Thymosin Beta-4 (43 amino acids) from Peptide Sciences. It is the most affordable entry point for labs exploring actin-regulation and cell-migration research with this peptide.
Thymosin Beta-4 in Cell Biology Research
Thymosin beta-4 is one of the most abundant intracellular peptides in mammalian cells, where it binds and sequesters G-actin to regulate cytoskeletal dynamics. In preclinical studies it has been examined for endothelial cell migration, angiogenesis, wound closure, corneal repair and cardiac tissue models. Our TB-500 is the complete 43aa sequence rather than a short fragment, so it reflects the native molecule studied in most published work.

Why Start with the 2mg TB-500 Vial
A 2mg vial is ideal for in-vitro scratch-wound or migration assays and for confirming reconstitution procedures. Labs scaling up can move to the 5mg or 10mg format with identical specifications.
Quality Control, COA and Shipping
Quality documentation matters for reproducible research. Every vial is traceable to a lot number, every lot carries an HPLC chromatogram and mass-spectrometry report, and orders are dispatched quickly from the USA in discreet, temperature-protected packaging.
