Tislelizumab (HY-P99052, MCE) preparation froze after being stored at -20℃ for a week. Will the drug activity be affected in this case?
Can it still be used for experiments after thawing?
Are there any relevant stability data or operation experience for reference?
[Troubleshooting Questions are selected from MCE customer consultation emails.]
The buffer of this product does not contain antifreeze ingredients such as glycerol, and it is recommended to store it at 4°C. Freezing may damage the activity of the drug.
If freezing has occurred, a small amount of sample can be taken for preliminary testing after thawing: if the activity is not affected, it can continue to be used; if the activity decreases, it needs to be repurchased.
The answer to this question comes from MedChemExpress (MCE) Technical Support.
