ProteinSimple Goes Big with the Simple Western

Back to News

Santa Clara, California, July 21, 2014—ProteinSimple announced today that it has expanded the Simple Western product platform by launching a kit for the analysis of large proteins using Wes, Sally Sue and Peggy Sue. Now, Simple Western users can analyze proteins as large as 440 kDa while realizing all the benefits of the Simple Western—a fully automated, highly reproducible, truly quantitative assay.

The Simple Western eliminates a time-consuming bottleneck in protein research today—the Western blot. Traditional Westerns have real limitations. They require many manual steps, can take up to 24 hours to complete, and the results can be variable. The Simple Western eliminates the hassles of Western blot protocols—no messy gels, no transfer tanks, no blots, no imaging and no manual analysis. Simply load your samples, push a button, walk away and come back to fully analyzed, highly consistent data.

Until now, the Simple Western could analyze proteins up to 230 kDa in size. Now, with the introduction of the 66-440 kDa Master Kit, the Simple Western can quantify proteins as large as 440 kDa, giving researchers broader protein analysis capabilities with this platform.

"The Simple Western is rapidly becoming the technique of choice for users from a broad array of scientific disciplines and many have expressed the need for a broader size separation range," commented John Proctor, Director of Marketing at ProteinSimple. "We are excited to deliver this kit to address their needs and expand the application of the Simple Western."
