目前,在实验动物中定量测定肿瘤转移程度的方法较少或不能准确反映出肿瘤转移程度上的差别。本文试图介绍一种通过测定DNA 聚合酶α的活性来定量评价肿瘤转移程度的方法。实验所用肿瘤为小鼠Lewis肺癌及单层培养的B_(16)黑色素瘤细胞株。后者有较强
At present, there are few methods for quantitatively measuring the degree of tumor metastasis in experimental animals or can not accurately reflect the difference in tumor metastasis. This article attempts to introduce a method for the quantitative assessment of tumor metastasis by measuring the activity of DNA polymerase alpha. The tumor used in the experiment was mouse Lewis lung carcinoma and monolayer culture B_(16) melanoma cell line. The latter is stronger
