ProteinSimple Reinvents the Western Blot...Again

Back to News

Santa Clara, CA, April 2, 2012 — ProteinSimple today introduced Sally as the next member of the revolutionary Simple Western product family. Sally eliminates a critical bottleneck in large-scale protein research and biopharmaceutical development — manual Western Blot analysis. With Sally, researchers can perform 96 Simple Westerns in a single automated experiment.

For over 30 years, the Western Blot has been the most frequently used tool in protein research. However, traditional Westerns have significant limitations. They require many manual steps and can take up to 24 hours to complete. In addition, Western Blot results can be variable and are semi-quantitative at best.

With the 2011 introduction of the Simple Western, researchers were finally free from the pain of traditional Western Blots. The Simple Western eliminated 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.

Sally pushes Simple Western technology even further by delivering significantly higher throughput with even lower sample volumes. Sally can deliver nearly 50 times the throughput of a traditional Western with 50 times less sample.

“Interest in the Simple Western has been phenomenal,” commented Tim Harkness, CEO of ProteinSimple. “Sally finally delivers real automation, quantitation and reproducibility to the Western. We believe this product can truly improve the quality of protein research around the world.”

Meet Sally, Simon and the Simple Western family on April 1-4 at the American Association of Cancer Research (AACR) meeting in Chicago, Illinois or visit
