通过高温干烤和焦碳酸二乙酯(DEPC)两种技术除去核糖核酸(RNA)酶，在保证RNA的稳定性的情况下，在1．0%T,0%C的线性聚丙烯酰胺(即丙烯酰胺和双丙烯酰胺的总质量分数是1．0%，交联度为0%)筛分介质中，利用无胶筛分毛细管电泳技术对水稻中的总RNA进行了分析，整个分析过程在15 min内完成。利用5．0%T,0%C线性聚丙烯酰胺筛分介质，对水稻中的转移RNA(tRNA)进行了较为详细的分析，在30 min内可将tRNA分为两组共9个峰。该方法可用于植物中RNA的分析，具有快速、准确的特点。
: When the RNase was eliminated through baking at 200 ℃ or treated by diethylpyrocarbonate(DEPC), the total RNA of rice could be separated within 15 min using 1．0%T, 0%C linear polyacrylamide as sieving matrix and 7 mol/L urea as denaturant． The tRNA of rice can be separated into two classes and about nine peaks when high concentrated polyacrylamide sieving matrix (5．0%T, 0%C) was used． This technique could provide one of the rapid and accurate methods for the determination of RNA in plants．
