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