| 中文摘要: |
| 热带药用海洋生物芋螺产生的芋螺毒素(Conotoxin),已成为神经科学研究的有力工具药和新药开发的新来源。近来出现了从芋螺基因组DNA中克隆新型芋螺毒素基因的新方法．因而快速获得芋螺基因组DNA是分离多样性毒素基因、建立基因库及药用芋螺基因资源开发的前提。本研究采用不同的DNA提取方法．从6种芋螺的不同组织和器官中分离总DNA，经综合比较，建立了简便快速的提取芋螺总DNA的改良苯酚-SDS优化方法。 |
| English Summary: |
| Conopeptides (Conotoxin) derived from tropical marine gastropod, cone snail ( Conus ) venoms have been an useful tool agent in neuro investigation and new drug source. Recently, new method of Conotoxin genes cloning from Conus genomic DNA has been established. So to get Conus genomic DNAs rapidly is the basis for diverse Conotoxin gene isolation, gene bank construction and the medical source exploitation. In this report, different DNA extractions from different tissue and organs of six cone snail species were performed in order to optimize the DNA isolation methods. The optimized brief phenol SDS method was established which fit for cone snails genomic DNA extraction. |
