05:02Results: Cryogenic Insertion of a Pre-frozen Sample of Mammalian Cells Results in Cellular Intactness Similar to Never-frozen Mammalian Cell Samples
Presented here is a protocol for cryogenic transfer of frozen samples into the dynamic nuclear polarization (DNP) magic angle spinning (MAS) nuclear magnetic resonance (NMR) probe. The protocol includes directions for rotor storage prior to the experiment and directions for viability measurements before and after the experiment.
