How to obtain the useful biochdrical informaton on this scale is the new tren in the research fie1d of analytical chehascy therefore , single molecule detection , sing1e cell detection , dna ~ and the shaple dna analysis were one of the main research direeons ofanalytcal chendscy nove1 molecular probe and ultrasmali biosensor for real tiine and in vivo detection has been the focuses in the research field of analytical chendstry according to the above mentioned advanced direetions , two pnd of inveshgations has been pdrirmed in thes thesis 人们对生命现象的观察和研究已经深入到纳米尺度和单细胞，单分子的水平，如何在这样一个尺度范围内获取有用的生物化学信息对分析化学的各个研究领域均提出了新的要求。单分子、单细胞检测、生物芯片的开发以及纳米技术的应用渐渐成为现代分析化学研究的主流领域之一。可进行实时、在线、原位、活体检测的分子探针和超微型生物传感器成为人们研究的热点和重点。
Restriction fragment lenth polymorphism ( rflp ) analysis n random amplified polymorphic dna analysis [ rapd ] , the sequence analysis of internal transcribed spacers ( its ) of ribosomal dna ( rdna ) , induction of microcyclic conidiation , sem ( scanning electron microscopy ) ascosporal isolation and other methods were applied to study more than 100 specimens or isolates of cordyceps , its anamorphs and other entomogenous fungi 本文采用了rapd 、 rdnaits的rflp 、 rdna的its序列分析、诱发微循环产孢、扫描电镜观察、子囊孢子分离等方法研究了虫草及其他虫生真菌的100多个标本或菌株。
After dna analysis , six white pigs is not present chimerism in various tissues . to one skin pigment piglet , chimerism is present in skin , brain , pancreas , pituitary gland and blood , but not in heart , lung , liver , spleen , kidney , intestine and ovary . the detection of another skin - pigment chimera is similar to the analysis result of wzsp 通过dna分析进一步得出，所产8头仔猪，其中六头白猪体组织未发现嵌合现象；其中一头皮肤色素嵌合体猪的皮肤、大脑、胰、甲状腺、血是嵌合的，而心、肺、肝、脾、肾、空肠、卵巢这些组织并没有嵌合；另一头皮肤色素嵌合体猪的检测结果和五指山猪取得相似的结果。
