| 1. | Both chips were used to purify the dna from pcr products . the silicon chip was also used to purify dna from yeast bacteria . 2
经实验证明：这两种方法都可有效的对pcr产物中的dna进行回收，同时还利用硅芯片进行了酵母菌的dna提取，取得了较好的结果。 |
| 2. | 4 . genomic dna was extracted from some animal products provided by nanjing customs . partial mitochrondrial dna cytochrome b ( cyt b ) gene was amplified and sequenced
对南京海关送检的部分动物产品进行基因组dna提取， mtdnacytb基因的中文摘要pcr扩增和序列测定。 |
| 3. | Results show that pcr primer selection also plays decisive role in the methodology . two primer pairs considered universal to domain bacteria in previous reports did not work on our field sample
Dna提取和pcr的空白试验表明，本方法容易受到污染的影响，对实验材料和无菌操作的要求必须严格。 |
| 4. | One was fabricated by silicon using mems ( micro - electro mechanical system ) technology ; the other was fabricated by pdms ( polydemethylsiloxane ) through soft lithography , using magnetic beads to purify dna
制作了两类基于spe ( solidphasepxtraction )法的dna提取芯片-硅芯片和磁珠吸附的pdms芯片。 |
| 5. | Dna extraction from different specimens is the foundation of conservation genetics . it is difficult to extract total dna from tannage of chinese alligator with usual method
利用不同的实验材料提取适合研究的dna是保护遗传学研究的基础，而对于鞣制皮革，用常规的dna提取方法很难提到适合于研究的dna样品。 |
| 6. | However , both the ctab and sds - ctab methods were only adequate to be used to extract dna of some strains of penicillium , and the dna bands of some strains were clear , but others were not obvious
另外一些菌株则提取不出谱带清晰的dna 。而氯化苄法适合于供试的所有青霉菌株的dna提取，所有菌株的dna凝胶电泳图谱带清晰，效果很好。 |
| 7. | By using plant endogenous 18srrna gene as target , specific primers and probes were designed and optimized . after that the condition and parameter were optimized . we established the genomic dna quality identification system for pcr and real - time pcr
3 、以植物内源基因18srrna为靶标，设计、优化后筛选出特异性引物和探针，建立了以18srrna为目标的检测植物基因组dna提取质量的pcr与荧光pcr鉴定体系。 |
| 8. | Tea plant was the most important cash crop in the section . in this dissertation , a novel genomic dna isolation method , the genetic polymorphism and molecular discrimination of tea plant , the molecular and morphological systematics of section thea were systematically investigated
作者对茶树基因组dna提取方法、茶树(种内)资源遗传多样性、茶树资源的分子标记鉴别、茶组分子系统学和形态系统学等进行了较系统深入的研究，获得以下重要结果。 |
| 9. | Benzyl choeide method , ctab method and sds - ctab method ) were used to extract dna from eleven strains of penicillium , the results showed that the benzyl choeide method was able to be used to extract the dna of those penicillium strains , and bands resulting from gel electrophoretic separations were very clear
比较了ctab 、 sds - ctab 、和氯化苄这3种dna提取方法提取青霉dna的效果。实验结果表明： ctab法和sds - ctab法只能适合于部分青霉菌株的dna提取。 |
| 10. | Discussion in practice of the forensic material evidence , one that is chemical disposal special material to examine , for example material treated by formalin fixation and paraffin wax is needed to distinguish the source to identificate . because the formalin influence dna to be drawn directly , fixation time is the important variation factor among them
讨论在法医物证实践中，经过化学处理的特殊检材，例如福尔马林固定后的石蜡包埋组织块和切片的个人识别和来源鉴别，因为福尔马林介导的甲基化直接影响dna提取的效率，其中固定时间是一个重要的变异因素。 |
