What Is TB-500?
TB-500 is the laboratory name for a synthetic peptide based on thymosin beta-4 (Tβ4), a small, highly conserved protein found in nearly all nucleated cells. Thymosin beta-4 is best known as the main G-actin-sequestering molecule in the cytoplasm: by holding actin monomers in reserve, it influences how quickly a cell can assemble and remodel its cytoskeleton.
That link to actin dynamics is what makes TB-500 interesting to researchers. The peptide is used in cytoskeletal and actin-binding studies, in scratch and transwell cell-migration assays, in angiogenesis models such as endothelial tube formation, and in broader tissue-response research in vitro and in animal models. It is also studied side by side with other peptides to separate overlapping signaling pathways. V8 Peptides supplies TB-500 as a lyophilized powder in a 10 mg research vial.

Reconstitution & Storage for Research
Confirm the vial size on the bench before calculating. The relationship is always the same: milligrams of peptide divided by milliliters of diluent equals the stock concentration.
Concentration math
- Adding 2 mL of diluent to a 10 mg vial gives 5 mg/mL.
- Adding 1 mL of diluent to a 10 mg vial gives 10 mg/mL.
Choosing a target concentration up front (for example, 5 mg/mL from a 10 mg vial) keeps pipetting volumes consistent between experiments. The calculator will confirm any combination. To dissolve the powder, add diluent gently down the side of the vial and rotate it slowly; TB-500 normally goes into solution within a minute or two without agitation.
Storage conditions
Lyophilized TB-500 should be refrigerated at 2–8 °C on arrival and frozen at −20 °C if it will not be used soon. Keep vials sealed, dry and out of the light. Peptides containing methionine are prone to oxidation, so minimize the time a reconstituted stock spends at room temperature, store it at 2–8 °C, and aliquot to avoid repeated freeze-thaw cycles. Full details are in TB-500 reconstitution and storage.
Quality & Testing
TB-500 is supplied to a ≥98% purity specification. The certificate of analysis is generated for that batch alone, so the data in the report describes the same material that arrives at your lab.
