| 摘 要： | 选取5只采自广西北海的野生拟穴青蟹(Scylla paramamosain),分别采用非伤害性(血淋巴)和伤害性(肌肉组织)取样方法提取基因组DNA进行COI扩增和ISSR扩增,检测DNA质量。结果表明,非伤害性(血淋巴)和伤害性(肌肉组织)取样方法获得的拟穴青蟹全基因组DNA的OD260/OD280分别为1.75~2.01和1.81~1.94,全基因组DNA纯度均较高,质量不相上下。同时,两种取样方法获取的DNA扩增片段大小均在600bp左右,同一个体扩增带型也是一致的。非伤害性(血淋巴)取样方法提取的基因组DNA,在质量上可以媲美伤害性取样(肌肉组织)提取的DNA,可以用于其它分子生物学实验研究。

| Abstract: | The genomic DNA of five Scylla paramamosain which collected from Guangxi Beihai were obtained by nondestructive and destructive sampling and evaluated using the quality of genomic DNA and PCR amplification concerning target gene and ISSR.The result showed that the OD260/OD280 of the genomic DNA obtained by nondestructive and destructive samping were 1.75~2.01 and 1.81~1.94,respectively,which indicated that the quality and the purity of genomic DNA obtained by two different samping were roughly the same.At the same time,the length of target gene were about 600bp and the band patterns of ISSR of the same one were identical by either nondestructive or destructive sampling.There is no qualitative difference between the genomic DNA from nondestructive and destructive sampling.The genomic DNA from nondestructive sampling can be used in other molecular biology studies. |
