We recommend that MHC class I and class II tetramers be stored at 4∞C. While some investigators report storing tetramers at -20°C or -80°C, we have not tested the effect of freezing on tetramers. Also the manufacturer of the streptavidin-PE and streptavidin-APC solutions we use cautions against freezing.
