线性质粒 meaning in English

linear plasmid

The retention tune of each of the three main peaks of the antibiotic fr - 008 is entirety identical to candicidin , except for one peak ( fr - 008d ) , which can also be seen as a very weak signal on the hplc profile of candicidin with the same rt
因此可以推测，这两个菌株在表型上的差别有可能与链霉菌fr - 008中的线性质粒有直接的关系，但也不能排除染色体基因之间的差异。
The powder was then applied to a silica gel column chromatography charged with 80 % acetone in water and eluted with the same solvent . after concentrating and drying , relatively pure fr - 008 was obtained . hplc assay a comparison between antibiotic fr - 008 and candicidin has been made by studying the hplc separation profiles of antibiotic fr - 008 , candicidin and a mixture of both
对链霉菌fr - 008和灰色链霉菌imru3570的rflp分析发现，它们的染色体具有很高同源性； pfge的比较研究发现，这两个菌株的明显区别是链霉菌fr - 008携带有两个线性质粒，而在灰色链霉菌imru3570中则没有这两个线性质粒。
