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