Hello.
I have a question about the shelf life of Corning's NuSerum I that we use for the first days of primary culture of neurons from the rat embryo hippocampus. How long do you keep it at -20°C before it starts to degrade? We have been worried about premature death since this summer and we still have this solution to check. There is no expiration date, it is simply noted storage superior or equal to 3 months, which does not mean much. Thank you.
It should be used before 3 months, better to call the company/supplier and reconfirm.
Thanks, but it is not what is written. They say storage >= 3 months. I think they tested at 3 month and not more, that's all. Usuallt serum like FBS can be stored for years. We buy a full lot that works, and avoid to change too often.
