FDD(Fluorescentdifferential display) was used to study the gene expression of embryonic lethality of kiand normal egg during the early embryonic stage at mRNA level and to separate thetarget gene and clone it.

• 并运用荧光差异显示法（flourescent differential display, FDD），在mRNA水平探讨肾脏型卵（ki）胚胎致死与正常卵在初期胚胎阶段的基因表达，分离，克隆目的基因；
