Thymosin Beta 4 (TB500)

Store at -20°C for long-term stability (up to 24 months). Store at 2°C to 8°C for short-term handling. Always protect from direct sunlight and ambient moisture.

Allow the vial to reach room temperature before opening to avoid moisture condensation. Slowly introduce bacteriostatic water (or sterile research solvent) down the side of the vial. Gently swirl; do not vigorously shake or vortex to prevent mechanical denaturing.

Reconstituted peptide solutions should be kept refrigerated at 2°C to 8°C and evaluated within 21 to 28 days, or aliquoted into sterile micro-tubes and frozen once at -20°C (avoid repeated freeze-thaw cycles).
