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。

Some of the students I taught in the 80's and 90's are now in Beijing. They can still quote Lu Xun by heart, for instance:"Kong Yiji was the only long-gowned customer who used to drink his wine standing."

我八九十年代教的一些学生，他们有的在北京，到现在还能背出鲁迅文章的选段来，比如&孔乙己是站着喝酒而穿长衫的唯一的人&。
