TB-500 100MG — Thymosin Beta-4 Fragment | Tissue Research

TB-500 is a synthetic peptide related to thymosin beta-4, the 43-residue actin-sequestering protein. Suppliers use the name for more than one preparation — some for the full-length sequence, others for the shorter actin-binding region — so the exact form and sequence supplied is the one stated on the batch certificate of analysis, and that is the document to read before planning work with it.

Compound data

Storage and handling

• Dry powder: store at −20 °C, sealed, protected from light and moisture.
• Bring the sealed vial to room temperature before opening — lyophilized powder is hygroscopic and draws moisture onto a cold surface.
• After reconstitution: refrigerate at 2-8 °C, protect from light, and avoid repeated freeze-thaw cycles.

What you need to reconstitute it

Material is supplied dry and has to be brought into solution before use. Bacteriostatic Water 20 mL is the standard solvent and is sold separately — step-by-step procedure in the reconstitution guide, and a comparison of solvents in bacteriostatic water vs sterile water.

Documentation

Every batch is third-party tested: HPLC for chromatographic purity, mass spectrometry for identity. New to batch documents? See how to read a COA, what 99% purity actually means and net peptide content vs gross weight and the full COA reading guide.
