当前玻璃纤维滤纸在生物样品软β射线的测量中已日益广泛应用。但国内过去尚无此类滤纸供应。我们在以前的工作中曾用酸碱消化法对组织细胞内核酸等生物大分子进行均相测量,处理样品时方法比较繁杂,实验周期长,成本也高。为此,我们与上海红光造纸厂配合,摸 At present, glass fiber filter paper has been widely used in the measurement of soft β-rays in biological samples. However, there is no such filter paper supply in China in the past. In our previous work, we used acid-base digestion to measure homogeneously biological macromolecules such as intracellular nucleic acids. When the sample was processed, the method was complicated, the experiment period was long and the cost was also high. To this end, we cooperate with the Shanghai Hongguang Paper Factory, touch
