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