No. Freeze-dried items have a residual moisture content below 1% and are hygroscopic, so they must be protected from moisture during storage. Oxygen can negatively react with the product (affecting culture viability) and is directly proportional to storage temperature. Therefore, long-term storage of lyophilized products should be kept at refrigerated temperatures under conditions that protect the sample from exposure to moisture or oxygen. Short term transport or storage (several weeks) at ambient temperatures should have no impact on the viability or performance of sealed vials of lyophilized material.
