The HOXA7 Colorimetric Cell-Based ELISA is a convenient, lysate-free, high throughput and sensitive assay kit that can detect HOXA7 protein expression profile in cells. The kit can be used for measuring the relative amounts of HOXA7 in cultured cells as well as screening for the effects that variuos treatments, inhibitors (ie siRNA or chemicals), or activators have on HOXA7.
