Summary

AFTER ANNEALING DURING THE GLASS TRANSITION TEMPERATURE RANGE OR AT SUB-GLASS TRANSITION TEMPERATURES, A < GLASS TRANSITION OVERSHOOT > WAS OBSERVED BY DIFFERENTIAL SCANNING CALORIMETRY IN VITRIFIED 55 AND 80% (W/W) GLYCEROL SOLUTIONS. BASED ON THE RESULTS IT MAY BE DESIRABLE TO MAINTAIN VITRIFIED BIOLOGICAL SYSTEMS AT TEMPERATURES SUFFICIENTLY BELOW GLASS TRANSITIO. THE RELAXATION EFFECTS MUST BE TAKEN INTO ACCOUNT PRIOR TO WARMING A BIOLOGICAL SYSTEM AFTER A LONG-TRCYPERAIN THESE EFFECTS SHOULD BE CONSIDERED IN STUDIES OF VITRIFICATION SOLUTIONS.
