The CAMK2A/CAMK2D Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor CAMK2A/CAMK2D protein expression profile in cells. The kit can be used for measuring the relative amounts of CAMK2A/CAMK2D in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on CAMK2A/CAMK2D.
