Hi Dinh,

You can ship but better to keep buffy coats in RNAlater solution for long term preservation and RNAase free environment.

But for both RNA and protein should be extracted in a shorter time frame, otherwise you will get degraded products.

For how long can I keep the cells?

I only need to transfer cells and then store them at -80 until the day of extraction. I am going to keep cells only for 1-2 weeks.
