TB500 (Thymosin Beta-4 Fragment) CAS No. 77591-33-4 TB-500 is a synthetic research-grade peptide raw material exclusively for laboratory study. It manifests as white lyophilized powder with HPLC purity no less than 99%. Each production batch is accompanied by full documentation, including COA and HPLC chromatogram for quality verification.

Solubility: Soluble in sterile water and bacteriostatic water. Storage Recommendations: Hermetically sealed lyophilized powder should be stored at -20°C under dry and dark conditions. Short-term storage at 2-8°C is acceptable. Once reconstituted, maintain the solution at 2-8°C and consume promptly. Avoid repeated freeze-thaw cycles, as this will degrade biological activity.
