LikesI have bought a variety of human and mouse Fc receptors from Acro, and the data showned very good stability. In addition, your protein can still produce pretty good data after repeated freeze-thaw cycles in the refrigerator. Love your products!!!
FAQ
- product
Can lyophilized proteins remain stable during room-temperature shipping or temporary room-temperature exposure?
In general, lyophilized proteins remain stable during room-temperature shipping or temporary exposure to room-temperature conditions.
Many ACROBiosystems recombinant proteins are supplied in lyophilized (freeze-dried) form. The lyophilization process effectively removes moisture from the product, helping reduce degradation-related reactions and improve protein stability during transportation and storage.
To evaluate the stability of lyophilized proteins under normal temperature conditions, ACROBiosystems conducted a stability study on 11 representative lyophilized protein products at 37°C. The study demonstrated that these proteins maintained good quality stability after storage at 37°C for approximately 20 days. Based on these validation results, temporary room-temperature exposure during shipping or handling is generally not expected to have a significant impact on product quality or downstream application performance.
To ensure optimal long-term stability, products should be stored according to the storage conditions specified in the product Certificate of Analysis (COA) upon receipt.
