TB-500
COA-backed · third-party tested
Structural class
TB-500 is a thymosin β4 fragment containing the actin-sequestering LKKTET motif, studied in cell-migration and angiogenesis assay models.
Pathways studied
TB-500 corresponds to the active fragment of thymosin β4 containing the actin-sequestering LKKTET motif. It binds G-actin with high affinity, reduces the G/F-actin ratio, and modulates cell migration and angiogenesis signalling in scratch-assay and endothelial models. As a short, highly soluble peptide it is typically straightforward to reconstitute in aqueous buffers.
Typical research focus
Research designs using TB-500 commonly quantify changes in the G/F-actin ratio and downstream migration readouts, using actin-binding controls to confirm that observed effects track with the LKKTET motif rather than non-specific peptide load. Comparison against full-length thymosin β4 helps attribute activity to the fragment.

How to read a certificate of analysis, what purity actually measures, and how research peptides are stored and independently verified.
The questions researchers ask most.
Every batch is independently tested by Janoshik Analytical. Each product links straight to the lab's own record, so you can check the exact purity figure yourself before you buy — nothing to take on trust.
Keep vials sealed, dry, and out of direct light. Lyophilised (freeze-dried) peptides are stable at -20 °C; once reconstituted, store as noted on the product label. Full handling notes sit on every product page.
Order by 2pm for same-day dispatch from our Melbourne warehouse, otherwise the next business day, with tracked delivery Australia-wide. No customs, no border delays — it's already in the country.

Researchers who bought TB-500 also stock these.
It brings together 2 labelled variants: 5mg and 10mg, current pricing context, stock visibility, COA access, and internal links to related catalogue pages so a laboratory buyer can review the material from a single reference URL.
TB-500 is generally discussed as a thymosin β4 fragment containing the actin-sequestering LKKTET motif, studied in cell-migration and angiogenesis assay models. The most relevant background is sequence behaviour, pathway or receptor context where documented, and analytical consistency under controlled laboratory conditions.
Use the label, COA, and internal SOPs as the primary guide. In general, store the material under controlled laboratory conditions, minimise avoidable environmental exposure, and keep variant tracking records current.
Yes. This listing includes access to a product-specific COA, which should be reviewed before use so purity, identity, and documentation checks are aligned with the project record.
No. The page should be interpreted strictly in a research and laboratory context. It does not provide dosage guidance, treatment claims, or human or animal use instructions.
