I need to do some PBMC/WBC FACS analysis. How long can my whole blood be stored in EDTA tubes at 4oC so that the lymphocytes are still good to be stained with a florescently-labeled mAb?
First of all, my advice is to store the EDTA tubes at the room temperature and not the fridge. Second - all samples should be stored using the same storage time.
