The GluR5 Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect GluR5 protein expression profile in cells. The kit can be used for measuring the relative amounts of GluR5 in cultured cells as well as screening for the effects that variuos treatments, inhibitors (ie siRNA or chemicals), or activators have on GluR5.
