The hnRNP C1/C2 Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect hnRNPC1/C2 protein expression profile in cells. The kit can be used for measuring the relative amounts of hnRNPC1/C2 in cultured cells as well as screening for the effects that variuos treatments, inhibitors (ie siRNA or chemicals), or activators have on hnRNPC1/C2.
