Active Motif's Ras GTPase Chemi ELISA Kit is the first ELISA-based kit designed to detect and quantify activated Ras GTPase. Because of its ELISA format, it is much more sensitive than pull-down/Western methods. This enables the detection of low levels of protein, while also using less sample. In addition, ELISAs are more quantitative than Westerns, and they eliminate the need to run and develop gels.
