The TGF ? Receptor II Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor TGF ? Receptor II protein expression profile in cells. The kit can be used for measuring the relative amounts of TGF ? Receptor II in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on TGF ? Receptor II.
