例句与用法

1. The pcr amplification products were separated on 6 % vertical denaturing polyacrylamide gels . numerous and distinct bands could be detected by silver staining
   Pcr扩增产物经6变性聚丙烯酰胺凝胶垂直电泳分离后，银染能检测到多而清晰的条带。
2. 92 distinct bands including 87 polymorphic bands and 24 specific bands were amplified from the genome dna of gastrodia elata bl . by using these selected primers belong to groups of opb , opi , opn , op w . the rate of polymorphic bands and the rate of specific bands were 93 . 5 % and 25 . 0 % respectively . seven often samples excluding tl , t3 and t9 were identified by the 24 specific bands
   随机引物opb - 5扩增出的特异性条带最多，有4条，特异性条带率达57 . 2 ，可以鉴定出m和t8两个样品；随机引物opn - 10扩增出的9条带中，有3条特异性的带，可区分m ， t8 ， t2三个样品。
3. Abstract : to decrease nonspecific products and obtain clear rapd patterns , 18 10 - mer random primers were tested at different annealing temperatures . the results indicated that all the amplification can be performed when the annealing temperature is in the range of 40 ~ 50 . there were a few primers with which the amplification was still performed when the annealing temperature is above 60 . by using high annealing temperatures , some primers which produce more nonspecific product at the annealing temperatures of 35 ~ 38 could generate reproducible and distinct bands
   摘要用38 66不同复性温度处理,比较了18条随机引物的扩增结果.发现复性温度在40 50之间均有数量不等的扩增产物,不同引物的最高复性温度不同,有些引物用60以上的复性温度仍有扩增产物.一些在35 38的复性温度下非特异性产物较多的引物,通过大幅度提高复性温度,能提高扩增产物的特异性,获得清晰的rapd带型。
4. These results suggested cultured areas and altitude played an important role in dna polymorphisms of gastrodia elata el . 30 primers which might produce dna polymorphisms from the genomic dna of cyathula offlcinalis kuan , were selected from 140 rapd primers among 7 groups . 232 distinct bands including 183 polymorphic bands and 52 specific bands were amplified from the genomic dna of cyathula offlcinalis kuan , by using these selected primers
   7 ， 6条特异性条带可区分出ni ， nz ， n3 ， n4四个川牛膝品系，可区分出的品系数目也是所有引物中最多的；在52条异性条带中， nz的特异性条带最多，达22条，其次是n3 ，共有13条。
5. The materials showed abundant polymorphism based on molecular level and the wild germplsms have less polymorphism than the cultivars . the number of polymorphic bands varies from 37 ( hekouyebajiao ) to 58 ( longxuan , huanong no 7 , heijiaomang ) , while the ratio of it is from 28 . 03 to 43 . 94 percent . 132 polymorphic distinct bands were obtained with two pairs of primers in this research , which is enough to distinguish the 60 materials from each other
   各种质之间的多态性带在37 (河口野芭蕉)到58条(龙选，华农7号，黑脚芒)之间，多态性比例在28 . 03到43 . 94之间，选用e - acc m - cat和e - acc mcag两对引物组合共扩增出132条dna条带，足以把60个材料分开。
