Most recombinant proteins are shipped at blue ice or room temperature. Lyophilization increases product stability, while reducing packing materials and shipping expenses. We have performed quality control tests on our lyophilized products where products are subjected to 37℃ for 3 days in a humidified chamber and found to be stable. These data demonstrate that lyophilized products shipped at ambient temperature and received with in a 3 day window retain full activity. We guarantee and support the product performance when delivered and properly stored within this timeframe. If the product was not delivered within 3 days to your facility or was not stored properly upon receipt, please contact Technical Service.
