Nuclear Transfer in Sheep

Somatic cell nuclear transfer is a complex and intricate procedure with a low success rate. Despite advances in embryo culture and the production of specialized tools and equipment success rate has remained poor. The procedure remains

针对同一指标，生化试剂盒和 ELISA 试剂盒的检测结果趋势是一致的吗？

，我公司的生化试剂盒采用的原理为：可见区的显色反应和紫外区的某一物质变化量。某物质与显色剂反应后，形成区别于自身的颜色反应，在某一波长下，吸光度的强弱与物质的含量呈正比关系，其显色反应的示意图如下： 生化测定结果的表现形式： ① 物质浓度：单位主要是mg/L、mmol/L、μmol/mgprot等 ② 某种能力和活力：世界上没有真实物质存在，以另一真实存在的物质变化量来表示其能力大小;其单位为U/L、U/gprot等。例如酶活的单位：在特定条件下，每分钟内转化1 μmol底物的酶量为一个单位(U

Genetic Modification of Sheep by Nuclear Transfer With Gene-Targeted Somatic Cells

For many years the lack of germline competent embryonic stem cell lines in livestock meant that the targeted modification of endogenous genes was not possible in these species. The demonstration that livestock could be cloned by nuclear
