1. Serum storage: It is recommended to store serum at -5 ℃ to -20 ℃. However, if stored at 4 ℃, do not exceed one month. If you are unable to use up one bottle at a time, it is recommended that you aseptically pack the serum into an appropriate sterilization container and then put it back in the freezer.

2. Method for thawing serum: It is recommended that you remove the serum from the freezer and place it in a refrigerator at 2-8 ℃ to melt it, then let it melt completely at room temperature. However, it must be noted that the melting process must be shaken uniformly and regularly.

3. What should be done if flocculent sediment is found after serum thawing? There are many reasons for the appearance of sediment in serum, but the most common reason is due to the denaturation of lipoproteins in serum, and fibrinogen (one of the proteins that forms coagulation) also exists in serum after thawing, which is also one of the main causes of sediment. But these flocculent precipitates do not affect the quality of the serum itself.

Serum should be stored at -5 ℃ to -20 ℃. However, if stored at 4 ℃, do not exceed one month. If you are unable to use up one bottle at a time, it is recommended to pack the sterile serum into an appropriate sterilization container and then put it back in the freezer.

After removing the serum from the freezer, it is first placed in a 2-8 ℃ freezer to dissolve, and then fully dissolved at room temperature. However, it must be noted that during the dissolution process, it must be shaken regularly and evenly.
