Simple Western™ assays on Jess™ are automated, capillary-based immunoassays that solve many of the challenges that come with traditional Westerns. All assay steps from protein separation, immunoprobing, detection, and analysis are fully automated. The variability in the manual processes that impact reproducibility, quantitation, time to result, and overall data reliability is eliminated. Best of all, the transition is simple—the same antibodies you use for Western blotting protocols can be used with Simple Western assays.
Your sample, separation matrix, stacking matrix, antibodies, and reagents are loaded automatically from a specially designed plate. Jess begins by aspirating the separation matrix and then the stacking matrix into each capillary. Next, your sample is loaded, and capillaries are lowered to make contact with running buffer. Voltage is applied to enable separation by molecular weight. Once the separation is complete, UV light immobilizes the proteins to the capillary wall. With proteins now immobilized and the matrix cleared of the capillary, Jess starts the immunoprobing process. In just 3 hours you'll have quantitative, size-based data ready for analysis.
