The OVOL1 Colorimetric Cell-Based ELISA is a convenient, lysate-free, high throughput and sensitive assay kit that can detect OVOL1 protein expression profile in cells. The kit can be used for measuring the relative amounts of OVOL1 in cultured cells as well as screening for the effects that variuos treatments, inhibitors (ie siRNA or chemicals), or activators have on OVOL1.
