Hello dear researchers,i have transduced my HEK293T cells with IL-2 and then puromycin screening was done, the cells were showing good egfp flourescence ,but then due to some reasons I have to store my cell culture at -80 degrees,and now after 2 months if I thaw and regrow my cells, will they be able to produce sufficient interleukin 2 protein?i am a little worried...
