Storage & handling

Up to 6 months in lyophilized form at 0-5°C. For best results, rehydrate just before use. After rehydration, keep solution at +4°C for up to 5 days or freeze at -20°C for up to 3 months. Aliquot before freezing to avoid repeated freeze-thaw cycles.

Confirm handling and preparation requirements against current product documentation and the requirements of your laboratory protocol.
