由于材料中存在大量的戊聚糖，无法直接测定RNA。它是由热的三氯乙酸萃取物的总磷含量与DNA的总磷含量之间的差异计算出来的，根据Z.4-32测定，这一过程只是因为发现(M.R.McDonald，未发表的数据)所测得的RNA的90%以上是经核糖核酸酶处理而酸溶的。由于EDTA的氮含量在较高浓度时太大，不能直接进行凯氏定氮分析，因此蛋白质的测定方法为0。首页--期刊主要分类--期刊细介绍--期刊题录与文摘--期刊详细文摘内容193,265-275,1951年和280 A.的吸收测量。
RNA could not be determined directly because of the high amount of pentosans present in the material. It was computed from the dif-ference between the total phosphorus content of the hot trichloroacetic acid extract and that of DNA, determined according to Z. 4-32, This procedure is justi-fied by the finding (M. R. McDonald, unpublished data) that over 90 per cent of the RNA thus measured is rendered acid-soluble by treatment with ribonuclease. Since the nitrogen content of the EDTA was, in the higher concentrations, too large to permit direct Kjeldahl analysis, pro- tein was determined by the method of 0. H. Lowry, N. J. Rosebrough, A. L.
