Protein Simple Peggy Sue Simple Western Blot System With Fluidics Station

The ProteinSimple Peggy Sue™ Simple Western Blot System is an automated capillary-based immunoassay platform designed to replace traditional Western blotting with faster, more reproducible results. Widely used in biotech, pharma, and academic research labs, Peggy Sue automates protein separation, immunoprobing, detection, and analysis within a single compact system.

By eliminating manual gel casting, membrane transfers, and subjective imaging steps, Peggy Sue delivers high-quality, quantitative data with significantly reduced hands-on time and sample consumption. The system supports size-based and charge-based assays, making it suitable for protein expression analysis, pathway validation, and biomarker research.

Peggy Sue is compatible with ProteinSimple assay kits and reagents and integrates seamlessly into regulated and discovery research workflows. Its automated operation improves inter-run consistency, while digital data output simplifies reporting and documentation.
