Storage & handling

Storage. Store lyophilized material at -20°C protected from light and moisture for long-term stability. After reconstitution, keep at 2-8°C and use within the documented in-use window.

Handling. Allow sealed vials to equilibrate to room temperature before opening to limit condensation. Reconstitute with the listed diluent using standard aseptic laboratory technique. Avoid repeated freeze-thaw cycles.

Safety. Handle as a laboratory research chemical. Wear appropriate PPE and follow your institution's chemical-handling and waste-disposal procedures.

Shipping

Dispatch. In-stock orders are processed on business days and shipped with temperature-controlled packaging and gel packs to preserve material integrity in transit.

Tracking. A tracking reference is issued at dispatch. Lab accounts can consolidate shipments and arrange standing orders.
