| Outline of Final Research Achievements |
Chromosomes (DNAs) of freeze-dried mouse spermatozoa could withstand high tempeature storage for short term (3 days to 1 week, 40 or 50°C) or long term (1 to 8 months, 25°C), when the spermatozoa were freeze-dried using EGTA/Tris-HCl-bufferred solution (ETBS) adjusted its pH values to 8.0 to 8.4, or using sodium-free ETBS containing potassium ions.
