The DNA isolated from rat virogenic XC cells transformed by Rous sarcoma virus retains standard transfecting activity for 7 months when the DNA solution in 0.1 X PBS, containing 10% glycerol is stored at -70 degrees C. The value of the sedimentation constant S20w does not significantly change during storage.
从经劳氏肉瘤病毒转化的大鼠致病毒XC细胞中分离出的DNA,当溶于含10%甘油的0.1X PBS中并储存在-70℃时,其标准转染活性可保持7个月。在储存过程中,沉降常数S20w的值没有明显变化。
