AB - In confirmation of Maximov's earlier results, non‐penetrating (sucrose) and penetrating (dimethylsulfoxide) substances lowered the frost killing temperature from ‐6°C in the control to ‐11° to ‐24°C, depending on the concentration. In contrast to his results, neither glycerol nor CaCl2 provided as good or as consistent protection. The addition of 0.05 M mercaptoethanol overcame this protective effect either completely (low concentrations of protectant) or partially (high concentrations). The effect of the mercaptoethanol occurs during freezing and not during thawing. Since ethanol, without the mercapto‐(SH) group, does not counteract the protective effect, such protection must be related in some way to the sulfhydryl group — perhaps by an effect on the disulfide and sulfhydryl groups of the proteins.
