The MAP2K7 (Phospho-Thr275) Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor MAP2K7 (Phospho-Thr275) protein expression profile in cells. The kit can be used for measuring the relative amounts of MAP2K7 (Phospho-Thr275) in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on MAP2K7 (Phospho-Thr275).
