Results pancreatic and salivary amylases with high specific activity and high purity were obtained. The apparent molecular weights of pancreatic and salivary amylases were 55kd and 57kd, respectively.
The process of photolyzing ADN was measured by IR analysis, the purity and apparent storage life of photolyzed ADN were tested by the liquid chromatogram.
通过IR分析检测了ADN的光解变化趋势，通过液相色谱分析了ADN的纯度和宏观光解储存寿命。
