查询词典 reagent

This novel reagent was treated with LDA to produce polystyrene-supported a-seleno carbanions, which reacted with alkyl halides and epoxides, followed by stereospecific selenoxide syn-elimination to give olefins and allylic alcohols respectively.

它与LDA反应形成α—硒基稳定的碳负离子，再与卤代烃或环氧化合物发生α—烷基化反应，烷基化后的树脂可以在30%的双氧水中进行氧化-消除，以良好产率和较高纯度合成了取代烯烃或烯丙基醇。

Tri- sodium citrate with aqueous gold chloride were warmed up and mixed to make gold sol; The chicken IgG(anti-JG04 strain GPMV) was immobilized to a defined detection zone on a porous nitrocellulose membrane, while 3A_5 was conjugated to colloidal gold which served as a detection reagent.

在加样处沾取含有GPMV的尿囊液样品，GPMV与金标3A_5结合形成混合液，由于层析原理，混合液向上移动，在检测线上混和液中与金标颗粒结合的GPMV与鸡IgG结合，由于大量GPMV沉积在检测线上，出现红线；而如果尿囊液中不含有GPMV，检测线上不出现红线。
