Reconstitution and handling

Allow lyophilised material to equilibrate before opening to reduce condensation risk. Add validated solvent slowly down the vial wall, avoid vigorous shaking, and record the final concentration in the laboratory notebook or LIMS.

Use aseptic technique, calibrated pipettes or syringes, and validated diluent choices for the assay system. Reconstituted materials should be aliquoted where appropriate to reduce repeated freeze-thaw exposure.

Storage

Store unopened material according to the stated condition: -20°C recommended (research-only). Keep vials sealed, dry and protected from light. Reconstituted solutions should be stored under validated laboratory conditions and discarded according to internal SOPs and applicable research-waste rules.

FAQs

What is TB-500 used for in research?

TB-500 is studied in actin-regulation, cell-migration, angiogenesis and inflammation-pathway laboratory models. It is a fragment of the naturally occurring protein Thymosin Beta-4.

How is TB-500 different from Thymosin Beta-4?

TB-500 is a synthetic version containing the active region of Thymosin Beta-4. It includes the key amino acid sequence responsible for biological activity.

Can TB-500 be combined with BPC-157?

Yes, TB-500 and BPC-157 are frequently studied together in cell-migration, angiogenesis and extracellular-matrix laboratory workflows.

How should TB-500 be stored?

Store lyophilised TB-500 at -20°C. Once reconstituted with bacteriostatic water, keep at 2-8°C and use within 4 weeks.

What purity is your TB-500?

Our TB-500 is ≥99% pure as verified by HPLC. Each batch includes a Certificate of Analysis.

What is the mechanism of action?

TB-500 promotes actin polymerisation, supports cell migration, enhances angiogenesis, and modulates inflammatory responses.

How do I reconstitute TB-500?

Reconstitute in sterile bacteriostatic water. Add solvent slowly and gently swirl to dissolve.

What sizes are available?

TB-500 is available in 2mg, 5mg, and 10mg vials.

What is TB-500?

TB-500 is a synthetic peptide corresponding to residues 17-23 of thymosin beta-4 (sequence: Ac-LKKTETQ). It is studied for its role in actin dynamics, cell migration, and tissue repair research. CAS number 77591-33-4.

How does TB-500 differ from BPC-157?

TB-500 modulates actin dynamics via thymosin beta-4 actin-sequestering mechanisms. BPC-157 primarily affects nitric oxide and growth factor signalling. Both are studied in tissue repair but via mechanistically distinct pathways.

Is TB-500 the same as thymosin beta-4?

TB-500 is a synthetic fragment corresponding to a biologically active region of thymosin beta-4, not the full 43-amino acid protein. It shares key actin-modulating properties with the parent molecule.

What purity is your TB-500?

Our TB-500 is ≥99% pure by HPLC with identity confirmation by mass spectrometry. Each order includes a lot-specific Certificate of Analysis.
