The TF3C2 Colorimetric Cell-Based ELISA is a convenient, lysate-free, high throughput and sensitive assay kit that can detect TF3C2 protein expression profile in cells. The kit can be used for measuring the relative amounts of TF3C2 in cultured cells as well as screening for the effects that variuos treatments, inhibitors (ie siRNA or chemicals), or activators have on TF3C2.
