Sally Sue

Sally Sue System - So frugal, so accurate, so easy
My sample is precious and I don't have enough for other methods
I have too many samples and need higher throughput protein characterization
My current method is not reproducible

So frugal, so accurate, so easy

Sally Sue™ lets you separate and analyze proteins by size from 2-440 kDa either by immunoassay or total protein. Got small sample volumes or starting materials? No problem. She uses as little as 0.2 µg/µL of protein in just 5 µL of sample, and runs up to 96 samples in one experiment. If you wish you could do more, Sally Sue gets you there!

Sally Sue Simple Western

The gel-free, blot-free, hands-free Simple Western is here! Sally Sue is an automated immunoassay using capillary electrophoresis. Sample loading, size-based separation, immunoprobing, washing, detection and quantitative data analysis are all done automatically, giving you a complete, walk-away solution. There are no messy gels, no transfer tanks or blots, and no film or imaging required. It’s just simple!
