The Rabphilin 3A Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect Rabphilin3A protein expression profile in cells. The kit can be used for measuring the relative amounts of Rabphilin3A in cultured cells as well as screening for the effects that variuos treatments, inhibitors (ie siRNA or chemicals), or activators have on Rabphilin3A.
