The CaMK2-beta/gamma/delta (Phospho-Thr287) Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor CaMK2-beta/gamma/delta (Phospho-Thr287) protein expression profile in cells. The kit can be used for measuring the relative amounts of CaMK2-beta/gamma/delta (Phospho-Thr287) in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on CaMK2-beta/gamma/delta (Phospho-Thr287) .
