And the gelose gel electrophoresis indicates that this large plasmid is about 22kb 对质粒dna电泳结果的分析表明，该质粒的大小约为22kb左右。
2.
The approaches used in the study included : observing the microstructure and ultrastructure of the cell line of colossoma brachypomum ( cbt ) and the cell line of carp ( cp ) stressed low temperatures under fluoroscopy and tem ; analysis of dna damage in the cultured cells under temperatures stress by dna gel electrophoresis 本研究采用的主要实验方法：通过荧光显微观察、电镜超微结构观察确定cbt (淡水白鲳臀鳍细胞)和cp (草鱼胚胎细胞)在低温处理后的显微与超微结构的变化。应用dna电泳分析细胞dna在低温处理后的断裂现象。
